Hunky "Dancing" star Mario Lopez partied it up at the Playboy mansion in this outfit. It's unclear what he's supposed to be, but who cares?! Clearly not the security guard!

Bootylicious Mario had a little trouble staying warm ... but just looking at this shot makes it hot up in here! Dancers have the best ... costumes.
