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."
