After parting ways with Sarah Silverman, his girlfriend of five years, in March, Jimmy Kimmel, 41, has found love again.
A source close to the Jimmy Kimmel Live! host confirms to PEOPLE that he has been dating Molly McNearney, a longtime staffer on his ABC show, for several months. Kimmel's rep also confirmed the news.
"After Jimmy and Sarah broke up, Molly and Jimmy both found themselves single, and they clicked," the source tells PEOPLE. "They're really happy together."
While the relationship may draw comparisons to David Letterman's recent revelations, the insider says, "during work hours, they keep things professional."
McNearney, 31, who first joined the show's staff as an assistant to the executive producer in July 2003, began writing on the show in 2006, and was promoted to her current position as co-head writer in May 2008.
Last year, Kimmel memorably declared he was "f–––king Ben Affleck" in a hilarious music video created as retaliation against a music video Silverman debuted called "I'm F–––king Matt Damon."
