Adrian Grenier
The Entourage star seems like the kind of guy who could grow a full beard two hours postshave. Good thing he can pull off either look.
Keanu Reeves
Lately, Keanu's been all about the big, full grizzly beard. Maybe he thinks it makes him look more like a serious actor who doesn't say, "Whoa, dude" all the time?
George Clooney
Oh, Clooney. Whether you're making strange beard faces or doing the glamorous movie-star thing, you just can't stop the charm.
Ryan Gosling
Clean-shaven Ryan is not amused, but get a little grizz going and he's more like, "Hey girl, how about we just sit here together and look at some pictures of your favorite celebrities?"
Penn Badgley
A little facial hair proves the Gossip Girl star is actually a real person. Dan Humphrey would never rock a beard. Well, at least not until he became a pretentious, bitter English professor whose greatest life accomplishment was being published in the New Yorker in high school.
