In honor of the American Music Awards [1] this Sunday, we're looking back on last year's epic night. From Nicki Minaj throwing shade at Jennifer Lopez's dance moves [2] to Julianne Hough and Nina Dobrev's girls' night out [3] to Ariana Grande's grandmother stealing the spotlight [4], it was a musical night to remember. But when it comes to big award shows, we dug a little deeper and found the best moments that you didn't get to see on TV. And since the AMAs are more like a relaxed party than a formal event, everyone from Harry Styles to Jennifer Lopez [5] let a little loose. Keep reading to see the night's best candid moments (including some between then-couple Demi Lovato and Wilmer Valderrama [6]), then check out Justin Bieber getting soaked on stage [7].
