The late-night host's video is a rebuttal to girlfriend Sarah Silverman's "I'm F---ing Matt Damon." The latest salvo, with Kimmel and a host of guest stars, including Harrison Ford and Brad Pitt, is called "I'm F---ing Ben Affleck."

The video has racked up almost half a million hits on YouTube and includes a "We Are the World"-style celebrity sing-along.

A number of stars, including Paul McCartney, have reportedly contacted the show to complain about not being included. (Read more Jimmy Kimmel stories.)
