Jimmy Kimmel has finally sought revenge on girlfriend Sarah Silverman, after she announced via video that she was f*cking Matt Damon (with the help of none other than her Bourne Identity-starring lover). Jimmy’s got a new video too, and well, you’ll have to watch it to see which hunky actor he’s f*cking. Let’s just say his name could rhyme with Zen Zaffleck, but you didn’t hear it from us. The vid is jam-packed with celebrity cameos - if you don’t want to try to name them all yourself, here’s who we spotted: Brad Pitt, Harrison Ford, Cameron Diaz, Joan Jett, Macy Gray, Robin Williams, Don Cheadle, Pete Wentz, Perry Farrell, Benji and Joel Madden, Lance Bass, Huey Lewis, Josh Groban, McLovin from Superbad, Christina Applegate, Rebecca Romijn, Dominic Monaghan, and Meatloaf.

Celebrities love to come out for a good cause - especially one that involves f*cking Ben Affleck.

The unlikely pair broke the bad news to Sarah’s longtime boyfriend Jimmy Kimmel with a music video, made to honor the fifth anniversary of his late night talk show. Sarah and Jimmy have been seriously dating almost as long as Britney Spears has been crazy, so things probably got pretty awkward after this vid aired, especially since Damon is Kimmel’s arch nemesis. But I feel like every dude should just expect that if his girl’s ever given the chance to bone Matt Damon, she’s gonna. It’s just one of those rules of life we ladies live by.
