You've heard of hand models - feet models - but what about bum models?  The always controversial American Apparel is looking for the perfect behind, to appear in their advertising and they're getting some cheeky entries. The call-out is for people 18 years of age or older to submit a close-up photo of their backside wearing American Apparel underwear, bodysuits or briefs for consideration.

The website will also allow for voting and commenting from users but the ultimate decision falls on the American Apparel judges. The top ten contestants as voted by the public will receive a grab bag of American Apparel goodies valued at $300 U.S.)

The contest started January 28 and will run until February 21, 2010.
