Miley Cyrus' model ex Justin Gaston (far right) has stripped off for a racy new advertising campaign for People for the Ethical Treatment of Animals (PETA).

Gaston joins aspiring model Giglianne Braga and wannabe actor Ben Elliot, his co-stars on online reality show "If I Can Dream," in the nude photoshoot, which aims to raise awareness about animal cruelty.
In one version of the ad, Gaston is pictured standing partially behind Braga to protect his modesty, while he cups her left breast to save her from completely baring her boob. In the photo pictured above, all three reality stars are covering their private parts with their hands.
And the 21 year old is happy to help with such a good cause.
He says, "With this PETA campaign, what I really wanted was it not to be about me but to be about the animals. We're trying to bring light to this cause.
Cyrus split from Gaston last summer.
