Rapper Nicki Minaj suffered a wardrobe malfunction while she was performing at a music festival here.

Minaj accidentally flashed her breast as she took the stage in a revealing outfit consisting of a black satin brassiere and matching thong underneath a fishnet bodysuit at the Wireless Festival on Sunday, reports aceshowbiz.com.

At first, the "Anaconda" hitmaker was seemingly unaware of the malfunction as she kept rhyming and dancing in front of thousands of festivalgoers at the Finsbury Park here.

Even after she found out about the incident, she just smiled and didn't seem to make a big deal out of it.
