George Clooney proves that once again, he's not like most guys. The actor, who recently split from waitress Sarah Larson, was spotted with a couple of "mystery brunettes" on one of his boats two weeks ago, prompting speculation that he was already on the rebound. But insiders tell E! News that George is taking it slow when it comes to getting back into the dating scene. "He is not dating anyone at all," says an E! News insider. "Anyone who says he is already dating doesn't know what they are talking about." In fact, George is using his freed-up time for work, not wooing, at his villa on Italy's Lake Como. "He's doing a lot of reading of scripts and writing," an insider tells E! News.
