American Music Awards 2016: Heidi Klum, Bella Thorne and Ariana Grande lead 'Worst Dressed' pack

The 2016 American Music Awards was filled some of the worst fashion disasters to date!

Stars hit the red carpet at the Microsoft Theatre in Los Angeles on Sunday in their most head-turning outfits -- and many probably should've checked a mirror before leaving home.

Singer and actress Kat Graham flashed her undies in a black sheer frock ... but she missed the mark with this look. Meanwhile, Vine star Lauren Giraldo looked like she was going to a circus with her bedazzled leotard and cape.

Heidi Klum gave us serious Goldfinger vibes with her metallic jumpsuit, while Julianne Hough's baby blue outfit left us totally disappointed.

Former Disney Channel stars KeKe Palmer and Bella Thorne may be two of the worst looks of the night. Palmer made jaws drop in a bizarre chainmail outfit and Thorne had us running the other way with her frightening look.
