The 2014 iHeartRadio Music Festival returned to Las Vegas’ MGM Grand Garden Arena for two days of the biggest music stars on the planet. Friday’s jam-packed lineup included Nicki Minaj, Ariana Grande, Usher, Taylor Swift, Jason Derulo, and Coldplay, with plenty of surprises.
Ariana served up a soaring set of her own with “The Way” and “Problem,” as well as new cuts off her No. 1 album My Everything. While her rumored boyfriend Big Sean was backstage, Childish Gambino joined her on stage for “Break Your Heart Right Back.”
