Oops:Nicki Minaj's Butt Implants shifts during stage performance.(PHOTOS)

It’s no news that plastic surgery rumours have trailed Nicki Minaj since her debut into the music scene. She was one of the unlucky few whose throwback pictures came back to hunt her when she became famous. New reports suggest that  Nicki suffered a “butt injury” during her Fashion Rocks performance on Tuesday night.

Sources close to her during her performance says “She hurt her butt when she stretched out.”
