Sarah Silverman is certainly not shy! The comedienne copped a feel of boyfriend Michael Sheen’s butt in full view of the cameras at Monday’s Met Gala in New York City. The 43-year-old Silverman apparently couldn’t resist showing a little affection for her British beau as the couple made their red carpet debut. Silverman and Sheen started going out in February, and the comic is going to be joining her beau on Masters of Sex for the second season.
