Billie Eilish is 24 years old in 2026. Born December 18, 2001, in Los Angeles, she will turn 25 on December 18, 2026. Few artists have compressed as many historic firsts into their early twenties as Eilish.
A Teenage Prodigy Who Redefined Pop
Eilish uploaded 'Ocean Eyes,' co-written with her brother Finneas, to SoundCloud at just 13 years old — it went viral and launched her career. By 17, her debut album When We All Fall Asleep, Where Do We Go? and its lead single 'bad guy' had made her a global phenomenon. At the 2020 Grammy Awards, at 18 years old, she swept all four major categories — Album, Record and Song of the Year plus Best New Artist — becoming the youngest person and only the second artist in history to do so.
Since then, Eilish has won an Academy Award for 'What Was I Made For?' from the Barbie soundtrack (2023), recorded the James Bond theme for No Time to Die, and released two further acclaimed albums, Happier Than Ever (2021) and Hit Me Hard and Soft (2024), continuing to collect Grammy wins into her mid-twenties.
