Bradley Cooper's face is handsome enough to pull off almost any haircut, but he's definitely hotter with some styles than with others. (Two words: top knot.) His latest look -- which he debuted on Monday, June 3, at a White House conference on mental health (above, left) -- is short, suave, and clean-cut.

Prior to his trip to the barber, the Hangover III star, 38, had been rocking longer locks, in part because of his role in David O. Russell's next movie. Back in January, the Oscar-nominated hunk said he had permed his hair for a screen test for the film; two months later, he was spotted on set with a head full of tiny pink rollers.

More recently, in May, the actor showed off a tiny top knot while traveling to Rio de Janeiro to promote the third Hangover film. The 'do created a bit of a stir, but Cooper probably didn't even notice.

"I just don't sweat the s--t. The small stuff. My mind is just less busy now. There were so many times when I would sweat the small stuff. All through my life. High school. College. As an actor," he told Details magazine in April.

"My dad's death allowed me to be more at ease with being myself," he continued. (Cooper's dad died in January 2011 after a long battle with cancer.) "And if someone's not going to like me, that's just the way it is. I used to think, 'Oh, my God. I don't want to make anyone not like me. I don't want to ruffle any feathers.' Now it's like, 'I'm just going to be myself and trust that. And I'm enjoying life more."
