Katy Perry thinks most awards shows are fun, but she especially loves the American Music Awards.
Perry is thrilled to open the live ABC broadcast Sunday night from the Nokia Theatre in Los Angeles with her latest single "Unconditionally."
"I appreciate all the other awards shows for what they are," Perry said. "Some are just kind of shock jock shows. Some are just like, 'Hey, let's see how many celebrities we can get together.' Some are actually legitimate like the Grammys, and the AMAs is a very legitimate show with musicality to it."
Three hours after Perry opens the show at 8 p.m. EST, Miley Cyrus will close things down. In between, most of the year's top performers are scheduled to take the stage, including Justin Timberlake, Taylor Swift, Lady Gaga, Rihanna, Luke Bryan and Florida Georgia Line, Macklemore & Ryan Lewis. Pitbull hosts and will perform with Ke$ha, and Jennifer Lopez will offer a tribute to Celia Cruz.
