Michael Sheen and Sarah Silverman Spotted Together

Sheen, who previously dated Rachel McAdams for two years, and Silverman, who famously dated Jimmy Kimmel, were seen flirting and laughing together. Whether the two are an item or not remains to be seen, and sources say that they are in the early stages of a romantic relationship.

“They are hanging out and having a giggle. We’ll see if it develops into anything more… She really makes him laugh. I wouldn’t call it dating, per se,” a source told E! News.

While one source insists they saw no public displays of affection, another source claims to have seen the newest celebrity couple making out.

“They were making out at Soho House. They were all over each other for a lot of the night,” a source told Us Weekly.
