Bradley Cooper is kicking butt and taking names as Lt. Templeton "Face" Peck in "The A-Team." But real life doesn't always imitate art, as Cooper admitted he isn't quite as tough as his onscreen Special Forces soldier. The real badass, he said, is his [article id="1640606"] "The Hangover" co-star Zach Galifianakis[/article].

"No one's tougher than Zach Galifianakis, who played Allen [in 'The Hangover'], so I don't even try to even compare anybody," Cooper told MTV News at movie's Los Angeles premiere on Thursday.

That may come as a surprise to fans looking forward to seeing the big-screen adaptation of the classic 80s TV series. "The A-Team" cast lineup — including Liam Neeson, Sharlto Copley and former UFC fighter Quinton "Rampage" Jackson — isn't exactly made up of wimpy guys.

Still, [article id="1638958"]MTV Movie Awards nominee Cooper[/article] insisted bearded funnyman Galifianakis, who is nominated for [article id="1640606"]Best Breakout Star[/article] at Sunday's show, was the dude to be most afraid of. "They won't make it," Cooper said of his other co-stars. "He's the toughest guy I ever met."

While Cooper was focused on Galifianakis, someone else was focused on Cooper. "The Hills" star Stephanie Pratt told MTV News she became a fan of the cute actor after seeing him in "The Hangover."

"The movie looks so funny," Pratt said. "I'm gonna say, I think I'm gonna like [Cooper] better in the 'A-Team.' "
