In honor of the American Music Awards this Sunday, we're looking back on last year's epic night. From Nicki Minaj throwing shade at Jennifer Lopez's dance moves to Julianne Hough and Nina Dobrev's girls' night out to Ariana Grande's grandmother stealing the spotlight, it was a musical night to remember.

Keep reading to see the night's best candid moments (including some between then-couple Demi Lovato and Wilmer Valderrama), then check out Justin Bieber getting soaked on stage.
