The 27-year-old singer was the first artist to take to the stage during music's biggest night, and he donned a black suit and green feather boa to sing 'Watermelon Sugar' backed by a band inside a circular room, where fellow performers Black Pumas, Billie Eilish and her brother Finneas, and Haim, could also be seen.

After Harry sang, Billie stood on top of a car to sing 'Everything I Wanted' alongside her sibling, and the former One Direction was a big fan of the performance as he could be seen putting his hands into his mouth to whistle appreciatively.

Haim then made their Grammy Awards performance debut with a rendition of 'The Steps' in front of a red background to close out the first musical interlude of the evening.

The evening's host, Trevor Noah, said of the segment: "I know that you haven't been able to go to a concert in a long time. So tonight we're bringing the concert to you."

And after Harry's performance of 'Watermelon Sugar' - which is nominated for Best Pop Single - drew to a close, the talk show host joked: "It's crazy to think someone that talented and handsome is from the same place as Boris Johnson."

Meanwhile, Billie - who is up for both the coveted Record and Song of the Year - has already scooped Best Song Written for Visual Media for her James Bond theme 'No Time To Die'.

She said: "It was a dream to make the song. I have no words. I can't believe this is real. I couldn't believe it was real then…"

Performing later on the show are the likes of BTS, Dua Lipa, Taylor Swift and Coldplay's Chris Martin.
