A second chance at love didn't work.
Despite a reconciliation that gave them both cause for laughs, late-night talk-show host Jimmy Kimmel, 41, and comedian Sarah Silverman, 38, have split, a source confirms to PEOPLE.
No reason was revealed for their second breakup. The funny duo dated for five years before they called it quits
last July. But they rekindled
their relationship just a few months later. "They're taking it slow," a source told PEOPLE last fall. "They're on the road back to being together."
The pair even managed to poke fun of their first split on Jimmy Kimmel Live!
last October when she was a guest and they exchanged awkward silences and quips like, "Did you make sweet love to anyone while we were apart?" RELATED ARTICLE:
