LeAnn Rimes has a message for anyone judging her thin physique: "I am completely healthy!"

The singer, who's in wedding planning mode in the run-up to getting hitched to fiancé Eddie Cibrian, added on her Twitter page Tuesday, "If people only saw how much I ate."

Recent photos show the singer, who is known for being in great shape, looking particularly slim. Referring to pictures of herself wearing leg-baring jeans shorts and an off-the-shoulder top as a "joke" and blasting the "judging" and "evil comments" that followed the photos' publication, Rimes also writes in response to a follower, "OVER It is right! I know how healthy I am, so really that's all that matters."

That same day she offered a glimpse into what she eats, citing her recipe to start the day: "Breakfast...poached eggs, whole wheat toast and Italian ham w/ fresh berries!" she wrote.

For those who still don't believe she's fit and healthy – and not wasting away as some have trumpeted online – she reminded one follower that "it's a photo....see me IN PERSON," and invited fans (jokingly) to see her stark naked.

"Maybe it's time for a nude pic so peeps can see how I look nowhere near what these stupid pics are trying to make me look like, LOL," she wrote, making it clear she was kidding.

A nutrition expert has told Radar Online that LeAnn Rimes could be suffering from 'pre-wedding stress' after reviewing new images that have appeared of the country superstar.

The latest photographs show Rimes, 28, looking super skinny as she stepped-out with her fiancé Eddie Cibrian, 37, in Calabasas, California, at the weekend.

Dressed in denim shorts and a baggy black t-shirt, the once toned performer had bony shoulders and stick thin legs on display.

Dr. Farid Zarif viewed the images of Rimes and compared them to ones of the performer from December of last year.

The health expert said: "Just as a lot of people have a propensity to gain weight others have the same ability to lose it too.

"There is definitely an apparent difference in her appearance and stress could be a factor with her wedding coming-up.

"A lot of women try to lose weight to look good in their wedding dress and somebody like LeAnn Rimes is under 'invisible pressure' to look a certain way for her fans also.

"In addition she is under more stress because she is constantly being followed by photographers and unlike the rest of us her appearance is constantly documented.

"It could be that she feels better and has more energy with her new shape and at this point I would not say the weight loss was alarming.

"If I was treating her I would find how many calories she was getting each day and make sure she was getting a healthy balance of protein, fat and carbohydrates in her diet."

In October the 28-year-old told Shape Magazine that she keeps herself in shape by boxing and circuit training.

After being slammed for gaining weight, Holly's World star Holly Madison bravely shows of her curvy body - flaws and all - for an exclusive unretouched photo shoot with Life & Style.

"I'd rather be overweight and curvy than super thin with no curves," Holly, 32, exclusively tells Life & Style at the photo shoot on Feb 21. "I'm proud of my body."

For good reason: Holly has a figure most women would envy. And yet, Holly isn't afraid to admit that her small stature doesn't exempt her from what haunts millions: cellulite. "I have cellulite -- and had it even when I was at my absolute thinnest," she tells Life & Style. "I'm never not going to have cellulite. People need to just accept that it's there and maybe dress accordingly or use body makeup to cope with it."

Still, when Peepshow's choreographer and director instructed Holly to shed weight -- after she'd gained 15 pounds following her move to Sin City -- she was hurt, she confesses. "Once I realized that other people were noticing that I'd packed on a few, I was embarrassed to go onstage," she reveals. Making matters worse: her Holly's World nemesis, model Jayde Nicole. "Holly needs to lose 10 pounds of fat," Jayde, who once cattily sent Holly a basket full of candy when she knew her co-star was dieting, recently told Life & Style.

"After moving to Vegas, I lived in a suite in Planet Hollywood for a year and ordered room service all the time," Holly says. "I like food too much to go on some crazy diet. French fries are my favorite downfall." Holly also says she's not willing to give up sweets but she has decided to make some healthy changes: Pilates classes and 20-minute runs, and mixing prepared meals from the Fresh Diet delivery service into her menu.

"I've always had a butt, and I want to keep it -- cellulite and all. I'm not perfect, but I love my curves." Holly tells Life & Style.

Most women would kill for a body like Holly Madison's, but Jayde Nicole, a co-star on Holly's World, isn't so envious.

"She needs to lose 10 pounds of fat," Jayde tells Life & Style. "If she lost 10 pounds and toned up a little bit, she'd be back in the shape she used to be."

Holly, a former Playboy Playmate, recently put on some weight, prompting the producers of her Las Vegas burlesque show, Peepshow, to demand that she shed the added pounds. Rather than coming to Holly's defense, Jayde tells Life & Style she agrees with the honchos.

"To star in a show like Peepshow, you want to be in the best shape you could possibly be. And Holly would never get picked for Playboy now," adds Jayde. "If you're a model, you're expected to be in good shape. That's your job."

Khloé Kardashian recently admitted that for her, weight is a "lifetime struggle." But the E! reality star won't end her body battle without a fierce fight.

"I'm in a working-out process, and I'm definitely back on trying to lose weight," Kardashian, 26, told PEOPLE Friday while promoting her Kardashian Glam Shapes SillyBandz at Kitson in L.A. "It's about being healthy, though. I believe in working out, eating well … I do everything in moderation. I don't like people who do extreme, crazy diets."

The youngest Kardashian sister wants to be a role model to others with similar struggles.

"I don't know if people think celebrities don't have insecurities, but … everyone does," she says. "Mine personally is weight. I could be as skinny as ever, but to somebody else, I may not ever be good enough. My weight fluctuates, and I accept that, and it's my life struggle, but I just wanted to point out that I'm normal, and everybody has their own things."

Fueling her is a desire to feel sexy again in a bikini. "That's my mission," she says. "I'm going to Mexico in June."

Kardashian also joked that by then she might even be ready to wear a two-piece on the cover of PEOPLE.

Producers ordered former sexy Girl Next Door Holly Madison to slim down for her role in burlesque Las Vegas show Peepshow, she told Radar Online in an exclusive new video interview.

Madison was "shocked" when she was told she's too fat, and needed to drop some pounds for the hit stage production.

"I always thought I looked fine. It was a shock to me when they told me to lose weight," the former Playboy Playmate, 32, told Radar Online.

"I'm still up in the air over what to do. I feel like I changed my eating habits to really healthy; I've lost a few pounds.

"I'm still getting there and deciding if I even want to lose weight.'

Madison, the 5'7" blonde who was one of Hugh Hefner's three girlfriends, said she was comfortable with her weight.

"I just feel like I market myself as a sex symbol, I don't market myself as a fitness model or a professional dancer so I feel like the way I look is fine!" she said.

"I don't think I need to lose weight!"

Tune in to the season two premiere of her hit show Holly's World Sunday, which premieres on January 23 at 10:30 pm on E!.

Just how did Kendra Wilkinson lose her baby weight?

With a lot of hard work and trips to the gym "no matter what," she told Us Magazine at the shoot for Us Weekly's Top Transformations.

As the star of E!'s Kendra, Wilkinson says she usually logs 30 minutes to an hour in the gym for four days of the week. If it's in the morning, she'll have a harder, longer workout. If it's at night, she explains, she'll just do simple stretches and a good run.

"When I work out I just go based off of how I feel," the 25-year-old mother told Us. "It depends on how I'm feeling and what I did the night before."

Although she used to give into temptation, Wilkinson has found a way to fight them. "I take a little bite instead of the whole thing."

With 40 pounds lost, the hard work is paying off. "I feel like I'm on my way after a good workout to a body I love," she told Us.

After spending two months in New York City to film Kourtney and Kim take Manhattan, Kim returned to Los Angeles 10 pounds heavier. With her hectic schedule, not only did Kim indulge but without a trainer to push her, she also skipped regular workouts. She and Kourtney would "eat nuts and hot dogs from street vendors every day," Kim tells Life & Style. "It was crazy. We had no time to stop and eat well or even look for healthy food. We just had to grab what we could as we ran past the food carts."

Since then, she's been on a mission and in just two weeks, the 5-foot-2 bombshell is back to a size 2! She's committed to daily workouts with either her long-time trainer, Gunnar Peterson, or what she calls her early-morning "rise and grinds" at Barry's Bootcamp. "I'm doing vigorous workouts all the time," Kim told Life & Style at the Borders in Century City, Calif., between signing copies of Kardashian Konfidential. "I work out with Gunnar -- mostly weights. Then I do boot camp. I alternate every day. One day trainer, one day boot camp."

Kim also been eating portion controlled meals from Sunfare, a gourmet-meal delivery service that Britney Spears, Eva Longoria and other celebs also rely on. "It's the only diet I can stick to," Kim tells Life & Style. "It makes me eat healthy because the food [breakfast, lunch, dinner, snacks] is at my house when I wake up."
