Mel Gibson is getting divorced …but not from Ed Limato, I’m assured. My insiders claim the actor/director/producer/mogul isn’t leaving his longtime agent just because Ari Emanuel will co-run WMA-Endeavor. Others insist he will because, back in 2006, Ari publicly asked Hollywood to shun the actor after Gibson made that drunken anti-Semitic rant during an arrest. Limato, of course, jumped to WMA from ICM in 2007.
