Miley Cyrus' ex -- and former underwear model -- Justin Gaston, 21, and members of the online reality series If I Can Dream, are stripping down for a good cause.

Fellow cast members Giglianne Braga, an aspiring model, and Ben Elliot, an aspiring actor, join Gaston in the racy print ads. The threesome say they weren't nervous about being in the buff.

"If nudity is involved, especially because it's for a cause, I didn't see anything wrong with that," Braga says. "We're just supporting a good cause by being naked."

But the Web stars wanted to make sure that the protection of animals was kept at the forefront.

"With this PETA campaign, what I really wanted was it not to be about me but to be about the animals," Gaston says. "We're trying to bring light to this cause."

Other stars including Karina Smirnoff, Bethenny Frankel and Stephanie Pratt have also bared all for the animal rights organization.
