Billie Eilish, American pop singer
Billie Eilish Pirate Baird O'Connell ( EYE-lish; born December 18, 2001) is an American singer-songwriter. She first gained public attention in 2015 with her debut single "Ocean Eyes", which was subsequently released by Darkroom, an imprint of Interscope Records. The song was written and produced by her brother, Finneas O'Connell, with whom she frequently collaborates on music and in live shows. Her commercially successful debut extended play Don't Smile at Me (2017) charted in the top 15 in numerous countries, including the US, UK, Canada, and Australia.

Eilish's first studio album, When We All Fall Asleep, Where Do We Go? (2019), debuted atop the US Billboard 200 and UK Albums Chart. It was one of the best-selling albums of 2019, buoyed by the success of its fifth single, "Bad Guy", Eilish's first number-one on the US Billboard Hot 100. The following year, she co-wrote and performed the theme song "No Time to Die" for the James Bond film of the same name, which topped the UK Singles Chart and won the Academy Award for Best Original Song in 2022. Her subsequent singles "Everything I Wanted", "My Future", "Therefore I Am", and "Your Power" each peaked in the top 10 in the US and UK; her second studio album, Happier Than Ever (2021), reached number one in 25 countries.

Eilish has received several accolades, including seven Grammy Awards, two American Music Awards, one Guinness World Record, three MTV Video Music Awards, three Brit Awards, a Golden Globe Award and an Academy Award. She is the youngest artist in Grammy history and second overall to win all four general field categories—Best New Artist, Record of the Year, Song of the Year, and Album of the Year—in the same year. She was featured on Time magazine's inaugural Time 100 Next list in 2019 and the Time 100 in 2021. According to the RIAA and Billboard, Eilish is the 26th-highest-certified digital singles artist and one of the most successful artists of the 2010s.
