Michael Sheen and Sarah Silverman confirmed their romance over the weekend, when they showed PDA while strolling around LA. Rumors about the pair's new relationship [1] first popped up earlier this month, when Sarah was spotted at the Masters of Sex star's 45th birthday party [2] in Hollywood on Feb. 5. Sarah joined the A-list guest list, which included Kate Hudson [3] and Michael's ex Kate Beckinsale [4], and reportedly helped Michael drive all his gifts home. Michael is no stranger to dating beautiful women; in addition to Kate, he has also had a relationship with Rachel McAdams [5], whom he met on the set of Midnight in Paris. Sarah herself is used to dating famous men, as she had six-year romance with Jimmy Kimmel that ended in 2008. She was most recently connected to comedian Kyle Dunnigan, but the pair parted ways in December 2013.
