Billie Eilish is an American singer-songwriter and fashion icon, born on December 18, 2001. She gained global recognition with her viral hit Ocean Eyes (2015), and her debut album, When We All Fall Asleep, Where Do We Go? (2019), won multiple Grammy Awards, including Album of the Year. Known for her moody, genre-blending sound, she has continued to evolve with albums like Happier Than Ever (2021) and Hit Me Hard and Soft (2024).

Before Billie Eilish became a global superstar, she was deeply involved in music from a young age. She was homeschooled by her parents, which allowed her to focus on creative pursuits. At age 8, she joined the Los Angeles Children's Chorus, which helped her develop her vocal skills.

However, her true passion was songwriting—she wrote her first song at age 11 for her mother’s songwriting class. Her breakthrough came when she and her brother Finneas uploaded Ocean Eyes to SoundCloud in 2015. The song went viral, leading to her first record deal and launching her career.
