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.”
