Somewhere, the former Mrs. Jimmy Kimmel is having a good laugh- and not over his hilarious “I’m F#$%ing Ben Affleck” video. Jimmy and fellow comedian girlfriend Sarah Silverman have split, according to a report that was posted at Us Weekly earlier today, which was mysteriously removed moments later.

Late night host Jimmy Kimmel and comic Sarah Silverman have called it quits after five years of dating, a rep for the couple confirms to Usmagazine.com.

The break up was mutual, a source says.

Silverman, 37, was spotted at Hugos in West Hollywood on Saturday with a male friend.

“She really looked like she was in good spirits,” an observer tells Us. “She was laughing and smiling. Very animated.”

But a few minutes later, Silverman – who ate organic quinoa topped with fresh fruit – grew somber and became enthralled in a heart-to-heart conversation with her pal.

“She was talking and it looked like he was listening and then advising her,” the onlooker tells Us. “This went on for around 20 minutes.”

Mutual friend Jonah Hill – who has appeared in comedy skits on Kimmel’s ABC show – was dining in the restaurant and also stopped by to say hello.

“Jonah’s appearance definitely had an effect on her,” a witness tells Us. “They spoke for just a minute. And after he left, Sarah looked momentarily pensive.”

Kimmel, 40, and Silverman celebrated their five-year anniversary in February by creating parodies for his show about sleeping with half of Hollywood

Silverman began the faux rivalry with her tune, “”I’m F—king Matt Damon.” Kimmel joked to Us at the time that he “hope[s] they’re happy together!”

Kimmel got his revenge with “I’m F—king Ben Affleck” — starring Brad Pitt delivering a FedEx package, Harrison Ford blowing the couple a kiss and Cameron Diaz making obscene gestures.

The pair met during a roast for Hugh Hefner, where Silverman told the audience he was fat and joked he had no charisma — but that didn’t stop them from working together.

“He hired me to do voices on [Comedy Central’s] Crank Yankers and around the second season of that we started hanging out,” Silverman has said. “A while after that he kissed me.”

Kimmel separated from his wife Gina in 2002 after 14 years of marriage. Silverman has said she wouldn’t consider getting married until gay marriage is legalized.

Sarah and Jimmy just headlined a benefit concert in Manchester, NH, Sarah’s hometown. Sarah was the star of the show, with Jimmy serving as host. The concert was to benefit the theater group founded by Sarah’s mother, who still lives in NH.

Jimmy left his wife to hook up with Sarah, but somehow Sarah managed to dodge that “homewrecker” reputation so many other women get in her position. Maybe it was because Jimmy isn’t exactly a looker, and at the time, he wasn’t as famous and successful as he is now. Five years is a long time in Hollywood, and there sure are a lot of funny memories in the wake of their breakup.

Update by Celebitchy: The story is back up on US Weekly’s website, and may just have been waiting for some editing. It’s such a big story that we were on it right away and thought there was some funny business going on with US initially pulling it.
