Karina Smirnoff isn't holding back.

The cover of the Ukrainian babe's May Playboy issue has her in a black see-through bodysuit, while the Dancing with the Stars pro bares it all in 10 sultry images inside the magazine.

"As a dancer I've always embraced my body," says Smirnoff, 33. "I'm thrilled to show off my strong, toned physique in the pages of Playboy and celebrate my sexiness."

Set on a dance floor, Smirnoff is clad in nothing more than red ballet shoes that tie up to her lower thigh and red ballet ties that cover half of her arms.

Sometimes you just have an off night. And that seemed to be the case for Kendra Wilkinson, who landed at the bottom of the leader board on Dancing with the Stars Monday night.

"The scores suck," the reality star said of earning just 18 points – the night's lowest score – for her Viennese waltz with partner Louis van Amstel. "That's the way it goes. I didn't do a perfect job and I got the scores I got, and that's the way it goes."

After judge Bruno Tonioli's highly animated critique, head judge Len Goodman reminded him, "These people are beginners, Bruno. Don't be cruel."

Kendra admitted to having mixed feelings about the routine. "Going into it I didn't feel comfortable but when the music started I did feel comfortable," she said. "I felt in place. I felt like I did everything I could have done."

So what went wrong? "I had three missteps," she says. "It sucks because I didn't mean to do it. It just happened. But I moved on from it and I finished it."

Holly Madison's stint on Dancing with the Stars may have been short-lived, but she thinks her former Girls Next Door costar, Kendra Wilkinson, could go all the way to win the competition's coveted disco-ball trophy.

"She absolutely has a chance at winning," Madison 32, recently told PEOPLE. "She's a natural athlete and she's really competitive and she has a fan following, so I think she'll do really well and certainly better than I did."

Still, Madison says that no matter how Wilkinson fares, she should just enjoy herself.

"It's so much fun," Madison, 32, says about participating on the hit ABC show. "As soon as I heard Kendra was going to be on this season, I texted her and said, 'Try your hardest, but don't even worry about being competitive or how long you stay on the show.' "

The Las Vegas Peepshow dancer, who sat with Wilkinson's brother and hubby Hank Baskett during a recent DWTS taping, so far is impressed with Wilkinson's footwork on the dance floor.

Madison, who encourages the show's competitors to "have a blast," says her main advice is to live in the moment.

"You never know when you're going to go. It could happen for any reason," says Madison. "So just enjoy it from week to week."

Karina Smirnoff likes to push things to the limit: Aside from flying around the ballroom on Dancing with the Stars, she enjoys boxing, skydiving and shooting guns.

"I'm fearless and love the adrenaline rush," the dancing pro, 32, tells Playboy, underscoring the point by posing nude in the May issue.

Smirnoff, who this season is paired with leader Ralph Macchio, wears little more than a few red ribbons and a sultry stare as the first Dancing pro to strip down for the magazine.

"Sexy is the confident energy a person produces," she tells Playboy. "Sexy is the comfortable feeling of being who you are."

Karina Smirnoff will be the first pro on Dancing with the Stars to pose nude in Playboy, but the news didn't come as a surprise to her bosses.

Despite reports that producers angrily felt she hurt the program's image, a source close to the show says, "They did know ahead of time and they still gave her one of the best pairings."

Smirnoff, 32, is dancing with point leader Ralph Macchio. Her photo shoot was done before the season started and will appear in the May issue of Playboy.

Although no other Dancing pro has posed for the magazine, Smirnoff is not the first from the show to do so.

Co-host Brooke Burke and competitors including Kendra Wilkinson, Lisa Rinna, Pamela Anderson, Holly Madison and Denise Richards have appeared in Playboy.

Following Hugh Hefner's tweet that teased Karina Smirnoff as the May issue cover of Playboy, ABC reportedly is frantic about the kind of attention that "Dancing with the Stars" will get. "If Karina posed naked, she can kiss her dancing days goodbye," a show's insider told PopEater. "I hope for Karina's sake that this isn't true."

"DWTS", despite skimpy clothes and sexy dances, is categorized as family TV. Karina, reportedly has violated the terms of her contract by posing nude for the cover without getting a consent from the show's bosses. "ABC publicity department controls the image of this show with an iron fist. It's a cash cow and they are not going to allow its reputation to be soiled by a dancer who wants to do Playboy," an ABC source said.

In fact, the execs have applied the theory on host Tom Bergeron. "Just a few weeks ago, ABC PR stopped Tom Bergeron from doing a live webcast with an outlet they didn't approve of. I can only imagine is going on right now after Hef's tweet," the source added.

Karina's issue of Playboy would be out later this month, possibly while she's still dancing on the show with surprise favorite Ralph Macchio. Rep of the pro dancer and ABC are yet to comment on the report. But it's not likely that ABC will give Karina a harsh treatment because this season is featuring another woman who has posed for Playboy, Kendra Wilkinson.

Dancing with the Stars contestant Chelsea Kane’s biggest fan is former Laguna Beach star Stephen Colletti – and Radar Online has an exclusive picture of the two getting cozy.

The photo shows the two embracing each other at the after party following the premiere night of the latest season of Dancing with the Stars on March 21, in which Colletti was in attendance.

“Chelsea and Stephen are definitely into each other,” an insider who was at the party told Radar Online.

“I saw them kiss at least three times and they were being really lovey-dovey. You could tell he was just so proud of her.”

Just four days later Kane took to her Twitter account calling Colletti “handsome.”

“My apartment is appliance-less. Opened my door to a handsome @StephenColletti standing there with a brand new microwave. #thelittlethings,” she tweeted.

Before last week’s show Colletti tweeted his support saying, “@ChelseaKane dances her little/big heart out tonight and her hard work will show.”

Colletti, 24, infamously dated reality-TV star Lauren Conrad when they taped together on Laguna Beach and then briefly dated actress Hayden Panettiere.

Kane, a 22-year-old Disney star, previously dated The Summer Set lead singer Brian Dales – who penned the song Chelsea in her honor.

“I’m not sure how serious Chelsea and Stephen are yet,” the source told Radar Online.

“But it looks like they have a good thing going for now.”

Things will get personal on Monday's Dancing with the Stars when pro Louis Van Amstel hits the ballroom with partner Kendra Wilkinson and takes on the role of her husband Hank Baskett.

"Next week is definitely a more spiritual, sexy story. It's a love story," Wilkinson, 25, told PEOPLE of their upcoming performance. "It's about my husband and me. It's about how we fell in love and what went on behind the scenes of falling in love."

While there's practically no comparison between the dancer and the athlete, Van Amstel, 38, is ready to put his acting chops to the test.

"I'll take the challenge," he says. "If she has to take the challenge each week, I'll take the challenge in storyline week. I'll have to up my game."

Fortunately, the pro dancer has met the inspiration for his role – and walked away with a good sense of the man he'll be impersonating.

"They are a very huge, big inspiration to young Hollywood that you can have it all and still be down to earth, have love, have kids at a younger age ... and be very supportive of each other," Van Amstel says.

The meeting also gave Baskett, 28, the opportunity to share an important – though perhaps unexpected – suggestion with his wife's new partner. "He didn't even give me advice," Van Amstel says. "He gave me a green light. 'Push my wife! Do anything you want with my wife.' "

It’s been a sweaty scene in Los Angeles as of late, and Kendra Wilkinson opted for her own method of chilling out after Dancing With the Stars rehearsal.

The “Kendra” starlet exited a dance studio and poured water all over her top to cool down, giving the paparazzi plenty to get excited over.

It's only week two at Dancing with the Stars and emotions are already running high.

Just minutes before her quickstep with partner Louis van Amstel Monday night, Kendra Wilkinson says, "There was a moment where I just wanted to walk off the stage."

The reality star, who hopes the Dancing experience helps her overcome her stage fright, says she was rattled because she, like viewers at home, watched footage of her quickstep rehearsal. The video package showed the reality star in tears, emotional over the fact that she grew up a tomboy and now she's dressing like a lady and trying to perform highly elegant moves on the dance floor.

"I'm 25 – I'm at my quarter-life crisis," Wilkinson explains. "I'm growing up and I'm doing it while I'm on this show. And it's so funny – a lot of people don't want me to grow up. They go, 'What happened to you?' That's why a lot of times I'm so stressed out because when I do grow up, people push me down, and when I'm too much of a kid people are like, 'You have to grow up.' "

Though she had temporary second thoughts about stepping into the ballroom Monday, once her performance began, Wilkinson says, she felt secure.

"The audience pushed me through tonight," she says, noting that the fans in the audience who shouted, "I love you, Kendra," made all the difference.

"I'm so thankful for them," she says. "I'm happy people out there have faith in me. I know I can do this."

Battle of the blondes!

While Season 12 boasts multiple professional athletes, Kendra Wilkinson tells Us Magazine that she's more concerned about another competitor on Dancing With the Stars -- one not known for her athletic prowess.

"Kirstie Alley, that's my competition," says the reality star, 25. "Dancing With the Stars is not all about being a pro dancer, it's about personality and popularity."

And 60-year-old Alley, who's famously struggled with her fluctuating weight, is very popular, says Wilkinson. Indeed, George Lopez was blasted by fans last week after he compared the Cheers star to a pig on his show.

"I think Kirstie Alley represents for all women in America," says Wilkinson. "Kirstie is the all-American woman, so that's who my competition is."

But it's not just other contestants Wilkinson has to contend with. She's also balancing the show's grueling rehearsal and taping schedule with being a mom to one-year-old son Hank Jr. with hubby Hank Baskett.

"It's a lot easier than I thought it would be," says Wilkinson. "I like to teach him something new everyday -- it's my goal as a mother to do that."

If Dancing with the Stars were filmed in a nightclub, Kendra Wilkinson would feel more at ease.

"I need to think, this is the club and I need to go out there and show what I really got," the reality star – and DWTS contestant – told PEOPLE this weekend, while hosting a party at the MGM Grand's Wet Republic in Las Vegas.

The Kendra star, 25, who received a lukewarm reception during the first week of the ABC show, said nerves got the better of her and that that she simply needs to let loose and remind herself that she'll never be a professional ballroom dancer.

"I hate how everyone is taking this so serious. People just need to relax and look at it as entertainment, as funny, as fun," she said. "Don't look at it like we're supposed to be pros."

One of the best things about the show, she said, is that the intense practice sessions haven't affected her time with her 15-month-old son, Hank Jr., because he usually sleeps while she's practicing and wakes when she's home.

But, there is one thing she has to do on the show that she was not prepared for: getting "dolled up."

"I lived at the Playboy Mansion, and I was dolled up every now and then. This is like intense dolled up, blue eyeshadow and hair out to outer space," she said. "I didn't even recognize myself on TV. I was like, who is that? I looked like a mermaid."

Nobody at Dancing with the Stars was more relieved than Kendra Wilkinson to get Monday night's premiere performance out of the way. Before performing the cha cha on live TV with partner Louis van Amstel, Wilkinson was a bundle of nerves.

"In the cha cha you're not supposed to bend your knees but I had to or I would have passed out," Wilkinson said. "I was so nervous, I barely took a breath."

What worried her? In short, everything about performing.

"I have a fear of the stage, a fear of the audience," Wilkinson said. "[The bright lights of the ballroom] made me dizzy. But I pulled it out and the fact that Carrie Ann [Inaba] said I didn't miss one step made me feel so good."

Wilkinson wasn't the only person to get a case of pre-show nerves.

"When I got here at the beginning of the day I wasn't nervous at all," says two-time Dancing champ Cheryl Burke, now in her 11th season on the show. "But two minutes before the show I thought, 'I'm going to throw up.' "

"That's a sign of a professional – you get nervous before you perform," said Burke's partner, WWE star Chris Jericho. "I'm just happy we got that first one under our belts."

The first dance, Romeo said, "felt great. It's like taking that first shot in your first basketball game. You knock it out and then you know what you need to do to get your team to the next level."

Dancing's next performance show airs March 28 (8 p.m. ET) on ABC.

Hugh Hefner was among the audience at Monday night's Dancing with the Stars premiere.

The Playboy founder attended the 12th season's first performance night to support former girlfriend Kendra Wilkinson, who is one of the 11 celebrities competing for the Mirror Ball Trophy.

The 84-year-old, who attended with fiancée Crystal Harris, later tweeted: "We had a wonderful time tonight lending our support to Kendra on the season premiere of Dancing With The Stars (sic)."

Wilkinson sent a message to Hefner on her own Twitter account, writing: "Thank you so much for coming, so good seeing you guys."

The Kendra star, who performed the cha cha with partner Louis van Amstel, had earlier told fans that she was "nervous and excited" ahead of her dancefloor debut.

"I have been working my butt off getting ready for this and I can't wait to make you all proud on the dancefloor!" she wrote on her official website. "I've learned so much thanks to my incredible partner and teacher Louis. He has been so amazing and I couldn't have asked for a better dance partner."

For Kendra Wilkinson, Monday night's Dancing With the Stars premiere means more than just the start of the new season. It means she will officially bequeath diaper duty for her 15-month-old son, Hank, to her pro-football hubby Hank Baskett.

"Hank is in his off season, so he's going to be the man of the house," Kendra tells PEOPLE, noting that Hank is a more than capable Mr. Mom while she's working.

"We put together a schedule for the baby," Wilkinson explains. "We didn't want to just dump him off to a nanny or a babysitter. When Hank is playing football, I take care of the baby. Now Hank is in his off-season so he has time to be the man of the house. He will run the house and take care of the baby."

Wilkinson, who's competing against 10 other celebrities for the season 12 mirror ball trophy, says knowing that her boys will be together puts her mind at ease so she can focus on performing.

"It makes me feel so good the baby will be with Hank," Wilkinson says. "We're very hands-on parents so this is just perfect timing."

Dancing premieres March 21 (8 p.m. ET) on ABC.
