George Clooney 'comfortable with Stacy Keibler'

George Clooney reportedly feels comfortable with his new girlfriend Stacy Keibler.

The two, who were first rumoured to be dating early August, were spotted together at a number of parties in Toronto over the weekend. Clooney was in town for the city's International Film Festival.

"They were comfortable and affectionate and seemed socially poised as a couple," a source told Us Weekly. "The two clearly work not only as a pair, but also independently. [Stacy] really stood on her own. George was not overprotective and didn't have to look after her."

The witness continued: "She was confident in her own space. She would come over to [George] and rub his back, then separate from him again... I've never seen him more comfortable."

Keibler, who is a former wrestler, recently said that she likes "everything" about Clooney.

Clooney split from Elisabetta Canalis in June after almost two years of dating.
