Sarah Silverman and BF Michael Sheen are taking their relationship to the next level!
A much seXXXier level.
Sarah has joined her man's scandalous Showtime series Masters of Sex.
The HIGHlarious lady will be on the second season for a recurring guest role as Helen on the show about sexual pioneers of the '50s sexual revolution.
We wonder if Dr. Masters will be taking any of his tools to test drive on his new test subject??! LOLz!
We're sure Sarah won't mind playing his patient off-screen! HA!
