Billboard was on the scene at the American Music Awards on Sunday, Nov. 18. On the red carpet, we caught up with will.i.am to talk about his new single with Britney Spears, chatted with Kelly Rowland about her "Ice" video, Karmin on their evolution from being a YouTube cover band, the Backstreet Boys on turning 20 (wow!) and Linkin Park on the state of rock n' roll. And much, much more.
