"They were making out at Soho House," an eyewitness told Us Weekly
. "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."
Also in attendance were Sheen's Showtime co-star Lizzy Caplan, Nicole Richie, Jerry Ferrara, Kate Hudson, Demi Moore, Sheen's ex-wife Kate Beckinsale, and her new husband Lee Wiseman, Us Weekly said. Sheen and Beckinsale divorced in 2003 after eight years of marriage.
Silverman dated late-night host Jimmy Kimmel for five years, splitting for good in 2009. The funny lady appeared last month on Bravo's "Watch What Happens Live"
and was asked about her feelings on Kimmel's rumored narcolepsy diagnosis.
"I personally don't think Jimmy was ever narcoleptic. His doctor did say he was narcoleptic and basically put him on basically the 'Limitless' drug," she told Bravo's Andy Cohen. "He goes, 'I'm narcoleptic! I went to the doctor and I told him I fall asleep every day at like 3:00.' I was like, 'Yeah, everybody does! It's an hour and a half after lunch!'"
