See who we spotted on the red carpet.

Demi Lovato is vamping it up.

The songstress proved that she was as confident as ever as she performed — what else? — “Confident” at the 2015 American Music Awards on Sunday night. Sporting Marcel waves and a dark lip, the 23-year-old looked like a gothic vixen from the 20s as she performed in a black ruffle one-piece, fishnet stockings, and thigh-high boots.

Lovato later returned to the stage to perform “You Oughta Know” with Alanis Morissette to celebrate the Canadian singer’s iconic album, Jagged Little Pill, turning 20.
