A veteran of the High School Musical series, Rodrigo became the breakout music star of 2021, leading with her massive viral hit Drivers License and following with the aching album Sour and the single Good 4 U.

Rodrigo came into the night nominated for the night's top four awards — best new artist, album, record and song of the year — but lost the best song trophy to Silk Sonic.
"This is my biggest dream come true," she said.
Silk Sonic — the all-star union of Bruno Mars and Anderson Paak — opened the Grammys in Las Vegas with their high-energy, infectious fix of retro soul and funk by performing their 777.
