It was a big night for artist's last night at the Billboard Awards, so it was only appropriate that the night ended with a bang, which wasn't a problem for Salt-N-Pepa. Salt-N-Pepa closed out the award show by performing a few of their biggest hits. They sang 'Shoop', 'Let's Talk About Sex', 'Push It' and lastly, joined by the three singers in En Vogue, 'Whatta Man'. If that wasn't enough for you, don't worry, the group announced recently that they will have a Vegas residency later this year. What did you think about the Salt-N-Peppa performance?
