Despite recent reports that Clooney has already moved on from ex Sarah Larson, sources tell E! that Clooney is still licking his wounds—alone. "He is not dating anyone at all," says a source. "Anyone who says he is already dating doesn't know what they are talking about."

We're told that Clooney, rather than wining and dining the ladies on his annual summer vacation at his villa on Italy's Lake Como, has been playing host to friends and, believe it or not, getting work done.

"He's doing a lot of reading of scripts and writing," says a source in Italy.

So what about the supposed "mystery brunettes" that were seen on one of Clooney's boats back on June 14? Well, E! has identified the dark-haired beauties.

The older woman in the pics is the wife of a Clooney business associate, and the younger brunette is none other than our colleague Olivia Munn, host of G4's Attack of the Show, who was visiting Clooney with her boyfriend/close Clooney pal, actor Bryan Greenberg.
