The 2021 American Music Awards, hosted by Cardi B, had some of the biggest names in music perform at the Microsoft Theatre in Los Angeles Sunday night.

Silk Sonic -- made up of Bruno Mars and Anderson .Paak -- opened up the show draped in matching red velvet suits as they serenaded the crowd with their hit "Smoking Out the Window."

The K-pop sensation BTS also took the stage with Coldplay and got the crowd rocking with their collaboration "My Universe."

Afterwards, the group -- to no surprise -- took home multiple AMAs including artist of the year, best pop duo or group and favorite pop song for "Butter," which they performed to close out the show.

Olivia Rodrigo, who held the most nominations of the night, delivered a tender performance of her ballad "Traitor" barefoot and with her guitar in tow. She went home with the AMA for new artist of the year.
