The annual Billboard Music Awards aired Sunday night and it was another eventful live show experience. The night kicked off with a 10-minute medley performance of Britney Spears hits delivered from the princess of pop herself before hosts Ciara and Ludacris took over to do what they do best - deliver a number of outfit changes throughout the show. Here's what the night's highlights included:

The Weeknd dedicated his Top Hot 100 award to Prince during the first win of the night, before Wiz Khalifa won the award for Top 100 Song. Meghan Trainer, Shawn Mendes, Justin Bieber, Blake Shelton and Gwen Stefani delivered some memorable performances (for good and bad) while Kesha SLAYED once she took the stage to perform her anticipated Bob Dylan cover. Celine Dion emotionally wrecked everyone watching when she accepted the icon award. And Madonna payed homage to the late great Prince. Watch some chart-toppers do their thing below.
