Michael Sheen dating Sarah Silverman?

Actor Michael Sheen and comedian Sarah Silverman have sparked dating rumors after they were seen arriving and leaving together from his 45th birthday party.
The couple partied together at the bash in West Hollywood on February 6, reported the New York Daily News.
"They were making out at Soho House. They were all over each other for a lot of the night. Sarah and Michael came and left together. She drove. When they left, Sarah opened her trunk so Michael could put all of his gifts in and then they drove away," a source said.
Sheen's ex-wife Kate Beckinsale also attended the party with her husband Len Wiseman.

Sheen and Beckinsale, 40, were married for eight years before splitting in 2003. He briefly dated VH1 personality Carrie Keagan, and then 'Notebook' actress Rachel McAdams, before splitting from her in February last year.
Whereas, Silverman dated fellow comedian Jimmy Kimmel for five years until they split in 2009.
