The 27-year-old singer - who is nominated for Best Pop Vocal Album for 'Fine Line', Best Pop Solo Performance for 'Watermelon Sugar' and Best Music Video for 'Adore You' - will kick off music's biggest night with an "incredible" performance, though it has yet to be announced what song he'll be singing.

Jack Sussman, CBS’ executive VP of specials, music and live events, told Variety: "You don’t want to miss the top of the show.

“It’s going to be music coming at you heavy and hard like you’ve not seen it before. We’ve got Harry Styles, this incredible entertainer, at the top of the show and we’ll just keep coming at you."

BTS will also be performing, with the K-Pop group set to make some "seismic activity in downtown LA."

Jack added: “It will be what you really love and want to see BTS do. They’re going to have fun and engage the audience at home. They’ll get you up on your feet in your living room."

And the executive insisted the show will be more than just a "remote Zoom telecast", with the cameras moving from live performance spaces inside the LA Convention Center to open-air tents outdoors in the LA Live plaza, as well as some pre-taped slots.

He said: “We wanted to do it right for the artists. It’s been a tough year. This is a moment in time for these artists to get out on stage and connect with fans who have been starving for these kinds of moments.

"We have a wonderful group of diverse musical talent -- some of the best live performers on the planet.

“For the viewer at home, this isn’t going to be a remote Zoom telecast. You’re going to be as entertained as if you were watching it at the Staples with 14,000 other fans."

Other performers at this year's Grammy Awards - which will be hosted by Trevor Noah - include Taylor Swift, Cardi B, Bad Bunny, Post Malone, Billie Eilish, Doja Cat, Miranda Lambert and Megan Thee Stallion.
