Real name and early life

Her parents, actors Maggie Baird and Patrick O'Connell, home-schooled both children in the Highland Park neighborhood of Los Angeles, where she sang in the Los Angeles Children's Chorus.
Career highlights
At 13 she recorded "Ocean Eyes," written by Finneas, and uploaded it to SoundCloud in 2015. It spread quickly and led to a deal with Darkroom and Interscope Records.
Her debut album, When We All Fall Asleep, Where Do We Go? (2019), topped the Billboard 200 and produced the No. 1 single "Bad Guy." At the 2020 Grammys she became the youngest artist to sweep all four general-field awards in one night: album, record, song and best new artist, per the Recording Academy. She won song of the year again in 2026 for "Wildflower."
She followed with Happier Than Ever (2021), whose title track became a fan favorite, and Hit Me Hard and Soft (2024), featuring "Birds of a Feather." With Finneas she won the Oscar for best original song twice: for the James Bond theme "No Time to Die" (2022) and for "What Was I Made For?" from Barbie (2024).
She has spoken publicly about living with Tourette syndrome. According to the Recording Academy, she has 10 Grammy wins from 34 nominations, and Biography.com notes she began writing songs in earnest by age 11, after joining the Los Angeles Children's Chorus at 8.
