There have been rumors that Nicki Minaj's supposed fake butt actually exploded at the 2014 "Fashion Rocks" event in Brooklyn. It was reportedly called a "butt injury." Here's what an anonymous source had to say about the incident,
"She hurt her butt when she stretched out. They were like they heard a pop. Since Nicki’s butt is fake, everyone thought her butt may have burst."
Her butt certainly doesn't look natural to me.
