The world's hottest bachelor is officially back!

George Clooney finally came out of hiding in Cancun, Mexico on Wednesday. At a photocall for his upcoming flick The Ides of March, the Oscar-winning actor, 50, sparked a frenzy among photographers and fans, flashing his famous grin, wearing a casual white polo and jeans.

It's the first big appearance for the sexy salt-and-pepper haired star since he and Italian model Elisabetta Canalis confirmed their split (on June 22) after two years together.

"I always knew that it wouldn't last," Manuele Malenotti, Clooney's best friend in Italy who introduced the pair, said recently. "All I can say is that George, when it comes to love, has decided that he is not going to get married again and he is not going to have any children and he won't change his mind."

Another insider recently told Us that Canalis, 32, was obsessed with the spotlight. "On vacations, she'd spend forever in her room, primping in her bikini, then go strolling on the beach for photographers to snap pictures of her," a source tells the new Us Weekly.
