Jimmy Kimmel, low-rated late nite host and our bestest bud in the whole wide world, has broken up with his longtime girlfriend, comedienne Sarah Silverman. And now we're told by an anonymous tipster that he has already taken up with a new lady. And not just any lady. Her name is Molly McNearney (Holly Johnson's just a character she played in a skit) and she's been promoted all the way (with one stop in between) from assistant to head writer for Jimmy Kimmel Live! by the sex problem-having former Man Show (ugh) host. No word yet on which aging Hollywood It boy she's fucking, but I'll bet it's Cole Hauser. Another picture, plus a larger version of the one above, await you after the jump.
