Jimmy Kimmel got revenge on longtime girlfriend Sarah Silverman and Matt Damon. (Remember earlier this month, Silverman admitted to effing Damon.)

Kimmel created a rebuttal music video revealing his newfound romance with Matt’s childhood friend Ben Affleck on the TV special Jimmy Kimmel Live: After the Academy Awards.

Jimmy enlisted the help of some of his hot shot friends which included: Harrison Ford, Cameron Diaz, Don Cheadle, Robin Williams, Huey Lewis, Rebecca Romijn, Macy Gray, Pete Wentz, Dominic Monaghan, Joel and Benji Madden, Josh Groban, Christina Applegate, Meat Loaf, Perry Farrell, Lance Bass, Joan Jett and Christopher Mintz-Plasse “McLovin” sang along with a gospel choir exhibiting solidarity for Kimmel and Affleck. There was even a special congratulatory cake presented to the host by a superstar delivery man–Brad Pitt!

Late-night talk show Jimmy Kimmel Live celebrated its 5th Anniversary tonight by revealing a surprise music video for host Jimmy Kimmel that included a priceless celebrity cameo.

Adorable show regular Sarah Silverman surprised her boyfriend and host with a pre-taped music video that was shot at the Delano Hotel in Miami last fall with Matt Damon. Watch the video below–and make sure to stick around for the hilarious dance moves!

It’s funnier if you know that Kimmel often says: “Our apologies to Matt Damon, we ran out of time” near the end of his show, a long-running gag lampooning instances where shows cannot feature their last guest due to time constraints.

Actor father Matt Damon was not far behind! And is that Luciana’s sister?

Papa Damon was seen pulling Isabella’s carseat out of the backseat of their chauffeured SUV while Luciana carried Isabella inside the airport.

The cute family had fellow travelers smiling as they made their way through security.

Earlier this week, Matt helped Isabella pet the animals at the Molly’s Mutts & Meows and Best Friends Animal Society adoption booth at a West Hollywood park along with Luciana. The family didn’t adopt an animal, but Isabella appeared to enjoy playing with the dogs, a park goer said.
