The ladies ruled the Billboard Music Awards. Following performances from Mariah Carey, Britney Spears, and Meghan Trainor, Nicki Minaj reigned over the MGM Grand Garden Arena in Las Vegas. After an introduction from Fifth Harmony, Queen Nicki kicked things off with her new single “The Night Is Still Young” before being joined by David Guetta for their dance collaboration “Hey Mama.” Nicki worked her famous hips, while Taylor Swift and Zendaya danced in their seats.
