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.
Silverman, 43, apparently couldn't resist showing a little affection for her British beau as the couple made their red carpet debut.
The bold grab was definitely in contrast to her demure dress.
The A Million Ways to Die in the West star looked chic in a bordeaux-colored Zac Posen duchess ball gown, while the Masters of Sex actor cleaned up in Prada.
