Sarah Silverman and Michael Sheen are dating, a source confirmed to PEOPLE on Wednesday.
The duo was photographed along with other stars on Feb. 6, the night Sheen celebrated his 45th birthday at West Hollywood hotspot Craig's.
Later, they were spotted together at Soho House nearby, E! reports.
The comedienne, 43, most famously dated Jimmy Kimmel on and off for years, while the Masters of Sex actor most recently publicly dated Rachel McAdams.
Sheen and McAdams parted ways about a year ago because Sheen wasn't ready to settle down with his former Midnight in Paris costar.
Silverman and Sheen are known to stay friendly with their exes. The funny lady – who recently appeared on Kimmel's late-night show to jokingly give him back the stuff he left with her when they dated –has said of Kimmel: "We were together for so long and tried our best to make it work. I can think of him now and don't have that edgy feeling anymore. I just love him to pieces."
Meanwhile, Sheen has managed to co-parent his daughter Lily with his ex, Kate Beckinsale.
A rep for Silverman did not return calls for comment.
