The Jonas Brothers ham it up backstage at the 2008 American Music Awards at the Nokia Theatre in Los Angeles on Sunday night.

Nick, Joe and Kevin took home the T-Mobile Breakthrough Artist Award (presented by Ashley Tisdale) thanks to thousands of votes from the fans. The trio were up against Paramore, Flo Rida, Colbie Caillat, and The-Dream. Congrats to the JoBros!

During their performance of “Tonight”, Joe and Kevin both sported Dior suits while Nick went for YSL pants and Band of Outsiders jacket and tie. Check it out below:
