1. Her full name is Billie Eilish Pirate Baird O’Connell. And she has older brother Finneas to thank for the unique middle name as she revealed in her book Billie Eilish: In Her Own Words that it was due to his love of pirates as a 4-year-old.
2. Billie recorded her hit song “Ocean eyes” at only 13 years old. “I was really into this boy with this curly brown hair and these deep blue eyes,” she said during a 2017 interview with CBS’s Los Angeles Affiliate KCAL. “Whenever I looked at him I just, like, got lost in his ocean eyes.”
3. Before musical fame, she recorded background dialogue for group scenes in movies. “I was in Diary of a Wimpy Kid, Ramona and Beezus, X-Men,” Billie told Rolling Stone in 2019. “It was fun—a bunch of random kids in a room yelling random things, and then we’d have a break and get snacks.”
4. As a child, she worked at a stable in exchange for free riding lessons. Since her meteoric rise to fame, she’s returned to the sport, telling the Rolling Stone that it’s “more for [her] mental health than like a hobby.”
5. Billie used to have a severe case of bieber fever. When she announced her collaboration with Justin Bieber on “Bad Guy” in July 2019, she revealed her fandom by sharing a hilarious childhood photo of herself standing in her childhood bedroom surrounded by posters of the teen heartthrob on social media.
6. She was diagnosed with Tourette's when she was 11. “I haven’t talked about it at all,” Billie said while speaking with David Letterman on Netflix’s My Next Guest Needs No Introduction. “The most common way people react is they laugh because they think I’m trying to be funny. They think I’m [ticking] as a funny move. And so they go, ‘Ha.’ And I’m always left incredibly offended by that.”
7. She’s the youngest two-time Oscar winner, with her and Finneas taking home the coveted award in 2022 for “No Time to Die” from the James Bond film and in 2024 for Barbie’s “What Was I Made For?”
8. She’s spoken publicly about her queer identity. “I’m physically attracted to [women],” Billie told Variety in 2023. “But I’m also intimidated by them and their beauty and their presence.”
9. She’s been vegan for more than a decade. “I learned about the dairy industry and the meat industry,” she told British Vogue in 2021. “Once you know about that kind of thing and you see it, it’s really hard to go back.”’
