BTS and Coldplay — two of the biggest groups on Earth — teamed up Sunday for a live and raucous version of their cosmic collaboration “My Universe” as the American Music Awards celebrated the best popular music for a second pandemic year with a mix of live and pre-taped performances.

Silk Sonic’s Bruno Mars and Anderson . Paak kicked off the awards on a funky, R&B and pre-taped note with their “Smokin Out the Window” and host Cardi B in a fur headdress — one of a constant stream of new outfits — revved up the crowd, admitting she was sweating.

“I’m a little nervous,” said the host after listing all the performances planned and noting that producers would be highlighting everyone’s home town. “We’re going to celebrate everybody.”
