The 31-year-old superstar showed off her good sense of humour by pretending to take a bite out of her chocolate bar clutch while posing for snaps on the red carpet.
Despite not taking herself too seriously, Lizzo still managed to look glamorous in her hilarious ensemble, with a runway-ready makeup look and up-knot hairdo.
Among the stellar lineup of nominees is recent Grammy winner Billie Eilish, who cleaned up at the 2020 Grammy Awards, taking home five out of six nominated gongs.
Joining Billie are other nominees Harry Styles, Lewis Capaldi, Mabel and Stormzy who is set to join previously announced BRITs Rising Star winner Celeste on stage.
More to come.
