Julianne Hough and Nina Dobrev headed out to the American Music Awards in LA on Sunday in what was probably one of the cutest girls' nights ever. Aside from their nonstop giggling on the red carpet, the girls also sat together inside for the show. This isn't the first time the pair have made people super jealous of their amazing friendship. They rocked out to Taylor Swift for a glitter-filled BFF date back in August. See Nina and Julianne's snaps here, and then check out the rest of the AMAs red carpet pictures!
