George Clooney is a "very cool dude," at least in the eyes of Sandra Bullock's son Louis, 3.

"If there was a choice between me and George … my son will leave to go with George and the guys," Bullock said today during a press conference, People magazine reports.

Bullock, 49, was speaking on behalf of her new movie "Gravity" at the Toronto Film Festival. The film puts the Oscar winner opposite Clooney, 52, for the first time on screen.

But apparently Louis would rather pay attention to Clooney than his mom.

"He's a boys' boy - he has to go and talk to the men," she added. "He asked, 'Where's George and Rande?' I'm like, 'What? I don't know.' He goes, 'I need them.'"

Only after Sandra caved and brought her son to the "Up in the Air" star for some male bonding, she said, "then I was allowed to take him back."

"The Blind Side" actress said if anyone is going to monopolize her son's time, it might as well be Clooney, someone she's known for more than two decades.

"George is a good man, and I'm really proud to have known him for this time and the human being he's become," she said.
