'If I Can Dream' star Justin Gaston gets naked for PETA. Yes, Miley's ex

Talk about a great way to get a lot of attention for a new Web series.

Justin Gaston, whom you may remember from being Miley Cyrus' super-cute underwear model boyfriend, and hot newcomers Giglianne Braga, and Ben Elliot have shed their clothes for PETA, the animal rights organization.

All three are on the new 24/7 Hulu reality show "If I Can Dream," the brainchild of "American Idol" and So You Think You Can Dance" creator Simon Fuller and 19 Entertainment.
