Celebs With Mustaches [PHOTOS]

Mustaches. They are polarizing and they can change a wearer's look drastically and dramatically, for better or for worse.

Some celebs look better with 'em than without, while others, like Justin Bieber, try desperately to grow some upper lip pubes but just can't get it going beyond a few errant hairs.

Then there's female celebs who like to play with fake 'staches. They can get away with it and not compromise their femininity since they're clearly faux and applied to their faces in goofy, silly fashion.

We've rounded up some of our favorite mustaches, both real and fake. We left off the milk mustaches, since those aren't made of hair. We had to draw the line somewhere.
