Nicki Minaj and Lil Wayne gave a live performance of 'High School' at the Billboard Music Awards Sunday night (May 19) and it was revealing in every sense.

On a set similar to a Miami mansion lined with palm trees and a sun set and beach in the background, Minaj and her twin backup dancers wined on the stage, rocking all-black.

The rapper rocked ripped leggings with a top decorate in gold spikes. She left the crazy colored wigs home and opted for all-black hair under her fitted hat.

At some point during the performance, Minaj walked to the middle of the stage where Lil Wayne sat onstage in a chair. She gave him a mini lap dance and poked her butt out to tease the crowd. "I'm the luckiest guy in the world," Wayne bragged after he got up.

Nicki then turned her behind to the crowd one more time, while Wayne pointed at it saying, "All that ass."
