After meeting in October at Kate Hudson's Halloween party, Ryan Phillippe and Amanda Seyfried had a fast moving romance complete with sweet set visits, breakfast with friends and dinner dates.

But after reports of a rift, the romance seemed to fizzle even quicker than it began – until Oscar week.

On Thursday night the pair were spotted at the Grey Goose Pre-Oscar bash at L.A.'s Soho House, which also included a special celebration for the Oscar-nominated films Biutiful and Winter's Bone.

Phillippe looked dapper in a suit while Seyfried was more casual, and they mingled on the back patio, chatting with friends before leaving together. "Amanda seemed a bit uneasy but they were very much a couple," says a guest.

Two nights later they hit a private bash in a bungalow at Chateau Marmont – only to head out together once again.

"They're figuring it out," says a source. "When it's good, they're really good together."

After three months of dating, Amanda Seyfried, 25, and Ryan Phillippe, 36, have called an end to their three-month romance.

“They are not dating anymore," a source reveals to Us Magazine. "And it’s not a big deal for either of them.”

That seemed clear on Saturday when Phillippe hit on Rihanna, 22, at the Gucci/Roc Nation brunch at L.A.'s Soho House.

"He said something to the effect of, 'What are you doing tonight?'" a witness tells the new issue of Us Weekly.

As for his short-lived fling with Seyfried, a second insider explains, "At one point, there was a chance it would develop into something more serious, but it never did."

Is Christina Aguilera ready to go public with her rebound man?

In Los Angeles Sunday, the star -- who filed for divorce from Jordan Bratman last month -- was photographed in L.A. holding hands with new guy Matt Rutler, a set assistant whom she met while making Burlesque.

It's definitely progress for the duo: The last time Rutler stepped out with Aguilera, 29 (during a Nov. 5 outing at L.A.'s Soho House with Nicole Richie and Joel Madden), he attempted to hide from the cameras.

"They've been on a few dates," a source told Us Magazine earlier this month, explaining that they reconnected after Aguilera's September separation from Bratman, her husband of five years.

Cautioned the source: "She's not looking to jump into a relationship right now. She...is focusing on spending as much time as possible with Max," her two-year-old son with Bratman, 33.

Rutler has been "really good for her and is helping her through this difficult time," adds the insider.

Ain't no other man like...Matthew Rutlet?

Weeks after her announced split from husband Jordan Bratman, Christina Aguilera has been seeking comfort in a brand-new guy: Matthew Rutlet, a set assistant whom she met while making her new film Burlesque.

"They've been on a few dates over the last few weeks," a source tells Us Magazine.

Indeed, despite his attempts to hide, Rutler was photographed escorting Aguilera, 29, on a Friday double date at L.A.'s Soho House with Nicole Richie and Joel Madden.

But, cautions the source: "It's not serious. She's not looking to jump into a relationship right now. She has a lot going on with the movie and is focusing on spending as much time as possible with Max."

Wed in 2005, the singer and producer Bratman, 33, have a two-year-old son, Max.

Aguilera and Rutlet befriended one another while making Burlesque, and reconnected after her September separation from Bratman.

"He's been really good for her and is helping her through this diffcult time," the source explains.
