Rihanna, Justin Bieber and Bruno Mars Perform at the Victoria's Secret Fashion Show

Rihanna, Justin Bieber and Bruno Mars all performed at the Victoria's Secret fashion show in New York City. Rihanna joked on the red carpet that she was going to suck in her stomach, throw back her shoulders and arch her back while she was on the runway next to the models. Justin said there was nowhere in the world he would rather be. Justin performed in an all white outfit that featured pants with a saggy, dropped crotch. We really wish he would move on from the M.C. Hammer pants look. Bruno Mars and his band performed "Locked out of Heaven" while the models strutted their stuff down the runway wearing a variety of crazy costumes. Take a look:
