It's no great mystery what Deadmau5 looks like without his helmet. Photos of Joel Zimmerman, the Canadian DJ behind the mouse mask, are all over the Internet, and he's performed and given interviews sans the giant LED-lit headpiece. Zimmerman's mug has also been plastered all over gossip websites, thanks to his on-again, off-again relationship with tattooed reality star Kat Von D, his former fiancee. Unlike fellow EDM superstars Daft Punk, Deadmau5 is a public figure -- a celebrity -- and fans the world over know what he looks like.

If you've never seen Deadmau5 sans rodent helmet, though, scroll down to see Zimmerman unmasked. He might not be the most handsome pop star in the world, but he's sold boatloads of records, rocked the Grammys and appeared on the cover of Rolling Stone. Mask or not, Deadmau5 is having his cheese and eating it, too.
