Nicki Minaj sang her song 'Super Bass' on the Billboard Music Awards before kicking off a remix of Britney Spears' 'Till the World Ends' that ended with Brit Brit making her second guest appearance of the night.

Following an introduction by Taylor Swift, Minaj walked onstage and saluted the audience along with her backup dancers, who were all dressed in striped bathing suits and matching wigs. Nicki and her dancers were then joined onstage by a bunch of shirtless men, who were all treated to lap-dances courtesy of Nicki and her crew.

After that, Nicki broke into the intro to the remix of Spears' 'Till the World Ends.' It was not long before Spears appeared onstage to perform the chorus of the hit song. Brit Brit, who earlier in the night joined Rihanna for 'S&M,' marched up the stage as she was followed by Minaj and her dancers. The performance ended with Spears and Minaj striking a back-to-back pose.
