During her appearance last night on her long-time boyfriend’s show, Jimmy Kimmel Live, Sarah Silverman debuted a special music video where she confesses that she’s been f*cking Matt Damon!

There’s been a long-running joke on Kimmel’s show where sometimes at the end of the night, the host will say something like “Apologies to Matt Damon, we run out of time” as if Damon was scheduled to appear, but got bumped. Kimmel has said there’s no real reason to continuously use Damon. When Damon did appear on the show in 2006, guess what happened? Yup … (watch that clip here). Too funny.

I love Silverman and find her humor hilarious. This video is good stuff, seriously WATCH IT — the video is here after the jump.
