(CNN)The 2016 Billboard Music Awards were held Sunday night at the T-Mobile Arena in Las Vegas, Nevada, and it was non-stop star power and performances.

If you didn't get a chance to see it, here's some of what you missed:

All is forgiven Britney Spears

This being Vegas, it seems only right that Spears should open the show.

After all, Spear's "Piece of Me" show is one of the hottest tickets in that town and she gave a pretty flavorful taste of it when she opened the awards show with a medley of her hits.

Wearing a red sequined, barely there outfit surrounded on the stage by dancers, she strutted and slinked all over the place. It more than made up for her less-than-stellar "Pretty Girls" duet with rapper Iggy Azalea at last year's Billboard Awards.

Spears was also honored with the Millennium Award.
