“I’m so surprised,” Raitt said in accepting the prize, after she walked to the stage with her jaw dropped open in shock.
Meanwhile, Lizzo won the Grammy for Record of the Year – the award honouring overall performance of a song – for her single “About Damn Time,” besting a crowded field including Beyonce and Adele.
Scoring the prize is something of a comeback for Lizzo, who was widely tipped to be the big winner in 2020 but lost all her chances at a major award to pop phenom Billie Eilish.
