You've gotta believe ~ Living my life in New York

Okay so most of us would say that Jake Gyllenhaal is a pretty hot guy. I know I wouldn't say no to of that action. But there's just something I can't seem to get a grip of, sure in the picture above we have a dream man, a guy with just about everything and a little more. He's got the looks, the charm, what else could you ask for.. So my qestion now is, why the 180? Why did he shave his head to look like a psycho-killer instead of just lookin' killer?!
