Billie Eilish Pirate Baird O'Connell, born December 18, 2001, in Los Angeles, California, is a globally acclaimed singer-songwriter known for her distinctive style and emotive performances. She rose to fame in 2015 with her debut single "Ocean Eyes," produced by her brother and collaborator Finneas O'Connell. Her debut album, When We All Fall Asleep, Where Do We Go? (2019), topped charts worldwide and featured the hit single "Bad Guy," making her the first artist born in the 21st century to achieve a U.S. Billboard Hot 100 number one. Eilish has won numerous accolades, including nine Grammy Awards and two Academy Awards, becoming the youngest artist to sweep the Grammys' four major categories in one year. Her subsequent albums, including Happier Than Ever (2021) and Hit Me Hard and Soft (2024), solidified her status as a pop icon while showcasing her evolution as an artist.

Finneas Baird O'Connell, born July 30, 1997, in Los Angeles, California, is an acclaimed American singer-songwriter, record producer, and actor. Known mononymously as FINNEAS, he has earned 10 Grammy Awards for his work, including producing and co-writing music for his sister Billie Eilish. He made history as the youngest winner of the Grammy for Producer of the Year, Non-Classical. Finneas launched his solo career with the EP Blood Harmony (2019) and has released two studio albums, Optimist and For Cryin' Out Loud! His solo music blends alternative pop with introspective lyrics, while his production work has shaped hits for artists like Selena Gomez and Camila Cabello. Finneas also contributed to film scores and won Academy Awards for songs like "No Time to Die" and "What Was I Made For?" cementing his legacy as a multifaceted artist.
