American Music Awards producer Larry Klein has teased that Justin Bieber’s set at tonight's ceremony performance will wow everyone. 

In a backstage interview, which was shared with the press, Klein explains that Bieber will close the show and described the young star's set as an “outrageous, outrageous finale": "His performance is a medley of songs, but each song has its own environment. It’s like a theatrical play.”

The AMAs will take place later tonight at the Microsoft Theatre in Los Angeles and other confirmed performers include 5 Seconds Of Summer, Nick Jonas, Demi Lovato, and One Direction. Fifth Harmony will present one of the prizes.
