British actor Michael Sheen and comedian Sarah Silverman are reportedly dating and have been spotted together recently.

A source talked to Us Weekly and said they witnessed the pair together in West Hollywood in the evening last week after Sheen's 45th birthday party.

"They were making out at Soho House," the source says. "They were all over each other for a lot of the night."

They also were seen together earlier in the night during his party. An insider at the party said, "Sarah and Michael came and left together. She drove." The source added that the actor was seen putting his birthday gifts into the trunk of her car.

Though many believe that the two are now an item, E! News isn't so sure Sheen and Silverman are together yet and has their own sources.

A source told the site that "it's very new right now so it's hard to categorize." They then added that he enjoys her company and "I wouldn't call it dating, per se."

Sheen currently stars on the Showtime program Masters of Sex, which was renewed for a second season.
