No Joke: Jimmy Kimmel and Sarah Silverman Split Again

Just months after deciding to make another go at romance, funny folk Jimmy Kimmel and Sarah Silverman have called it quits again.

"Sarah initiated the split this time," a source tells UsMagazine.com. "He's bummed."

The couple, who first started a-courtin' in 2003, parted ways for the first time in July 2008, only to reconcile in the fall. But it "seems like it's over for good this time," a sources tells Us. "[Jimmy is] sad because he just bought a new place and now has nobody to share it with."

Toward the end of their first stab at romance, Silverman and Kimmel famously poked fun at each other with viral videos. Hers claimed, "I'm F---ing Matt Damon," while his countered, "I'm F---ing Ben Affleck." Silverman's vid, which premiered on Kimmel's talker, went on to garner a pair of Emmys.
