Billie Eilish Pirate Baird O'Connell (born December 18, 2001) is an American singer and songwriter. Her debut single, "Ocean Eyes", went viral and has accumulated over 132 million streams on Spotify as of October 2018. Her debut EP Don't Smile at Me was released in August 2017. Following the EP's success, Apple Music named Eilish as its newest Up Next artist a month later in September 2017.
Eilish was raised in Highland Park, Los Angeles by a family of actors and musicians. Her parents are actress-musician-screenwriter Maggie Baird and Patrick O'Connell; she has mainly Irish and Scottish ancestry. She was homeschooled, and joined the Los Angeles Children's Chorus at age eight. At age eleven, Eilish began writing and singing her own songs, taking after her older brother Finneas O'Connell who was already writing, performing and producing his own songs with his band. In October 2015, Eilish recorded the song "Ocean Eyes", initially written by Finneas for his band, and sent it to her dance teacher who helped to choreograph a dance to it.
