The Backstreet Boys mixed the old with the new as they performed at the iHeartRadio Music Awards. On Thursday, the group took to the stage to perform their new song "Chances," but things took an unexpected twist when they started singing their 1999 hit "I Want It That Way." I'd be lying if I said I didn't scream at my TV screen. Those moves! Those voices! Yep, they've still got it. I, for one, can't wait to scream like a teenager during their DNA tour this Summer!
