Elisabetta who?

George Clooney has been the talk of the town at the 2011 Toronto International Film Festival after he arrived on the scene with his alleged new girlfriend, 31-year-old actress/model/wrestler Stacy Keibler. The duo partied together late into the night at the Grey Goose/Soho House pop up, and were not shy to show affection!

“They looked really happy, laughing with friends and were not shy to show affection” a source tells Celebuzz. “They stayed for a couple hours and seemed to really enjoy each other’s company.”

Though Clooney, who stars in two of the festival’s biggest movies, The Ides of March and The Descendants, has remained quite on the rumors, the 50-year-old bachelor was spotted leaving a party Saturday night with Keibler, leaving many to believe that they are indeed an item. Or at least something.

Clooney has had a long history of dating younger women. His most recent relationship, to 33-year-old Italian actress and Dancing With the Stars contestant Elisabetta Canalis, ended in June.

Will Clooney and Keibler last? Check out photos of them from Saturday and decide for yourself.
