Olivia Rodrigo, the teenage singer of heartbreak ballad 'drivers license', was crowned Best New Artist on Sunday (local time) at a Grammy awards ceremony that featured a surprise appeal for support from Ukrainian President Volodymyr Zelenskiy.
The 19-year-old, who performed her signature hit while seated on the hood of a white Mercedes on the Grammys stage, triumphed over Saweetie, Glass Animals and others to win the accolade at the televised ceremony in Las Vegas.
"This is my biggest dream come true. Thank you so much!" she said as she held her trophy.
However, she lost in the other three major categories she was nominated in as multi-genre artist Jon Batiste won Album of the Year and R&B duo Silk Sonic won Record of the Year and Song of the Year.
Batiste landed the night's biggest prize for We Are, an album inspired by the Black Lives Matter movement.
"I believe this to my core - there is no best musician, best artist, best dancer, best actor," Batiste said. "The creative arts are subjective ... I just put my head down and I work on the craft every day."
Silk Sonic, featuring Bruno Mars and Anderson.Paak, claimed the top song and record awards for their 1970s inspired hit 'Leave the Door Open'.
"We are really trying our hardest to remain humble at this point," joked Paak as the pair accepted the second honour.
Midway through the ceremony, host Trevor Noah introduced a video message from Zelenskiy, who contrasted the joy found through music to the devastation caused by Russia's invasion of his country more than a month ago.
"What is more opposite to music? The silence of ruined cities and killed people," Zelenskiy, wearing a green t-shirt, said in a hoarse voice.
"Fill the silence with your music," he added. "Support us in any way you can. Any, but not silence."
The remarks preceded a John Legend performance that featured two Ukrainian musicians and a Ukrainian poet.
The highest honours in music were postponed from January during a spike in COVID-19 cases and moved from Los Angeles to the MGM Grand Garden Arena in Las Vegas. Thousands of spectators packed the venue, a contrast to last year's scaled-down outdoor event.
Winners were chosen by some 11,000 voting members of the Recording Academy.
Noah urged the audience to think of the evening as "a concert where we are handing out awards".
"We are going to be keeping people's names out of our mouths," Noah added, a jab about last the Oscars slap by actor Will Smith, who told comedian Chris Rock not to mention his wife's name.
