The iHeartRadio Music Awards went all out on Thursday night. Not only was the award show filled with show-stopping performances [1], including Alicia Keys's precious performance with her son [2], but there were plenty of moments that you didn't catch on TV. The Backstreet Boys took us back to the '90s with their swoon-worthy appearance [3], and Taylor Swift caught her with a handful of stars [4] during the show. See some of the best moments of the night ahead!
