Miss BumBum 2012 Girls, Brazil

It's not always all fun and games though. The beauty pageant for behinds has had its share of scandal. Brazilian new site Globo reported that Cibelle Ribeiro, this year's favorite to win, was almost disqualified when judges suspected she might have butt implants and she refused to take an X-ray. Ribeiro has, however, since submitted to the X-ray, and is now back in the running for the crown.
