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!

On Thursday, it’s a collision of stars at Los Angeles International Airport.

Super smiley Kelly Clarkson looks relaxed and cheerful as she prepares for departure while a tired-looking John Mayer offers a tight-lipped almost smile as he makes his way to the parking lot.

Meanwhile, the cast of Superbad, including Michael Cera, Jonah Hill, and Christopher Mintz-Plasse (McLovin), runs amok in the airport, playing paparazzi. (Could Cera’s old school white camera and rolls of film be related to his recent trip to Samy’s Camera?) But, it looks like even they can’t make security checks fun.
