Salt-N-Pepa shut down the house at the 2018 Billboard Music Awards with a spectacular performance that had the entire audience on their feet. The ladies were joined by R&B group En Vogue to perform a medley of their hit songs, including "Whatta Man," "Let's Talk About Sex," "Shoop," and "Push It." Toward the end of the set, the iconic rap group was also joined by host Kelly Clarkson, who sang along and dubbed the moment "amazing." We couldn't agree more!
