Who Is Billie Eilish's Brother?

When Billie Eilish accepted her first 2021 Grammy virtually, her older brother, Finneas Baird O'Connell was sitting next to her (via Allure). "No Time To Die," which Eilish co-wrote with her brother, won the "Song Written for Visual Media" award. If you've seen Eilish's new documentary, you know that Finneas is more than just someone she works with. Finneas travels with the world with Eilish (via Chicago Sun-Times). At concerts, Eilish tells her audience that he's "my big brother and my best friend" (via Variety). The sibling's collaboration on "No Time To Die" isn't an exception: it's the rule. Finneas told Variety that "probably 75-80% of the songs are written with us sitting next to each other at a piano or with a guitar, singing a melody together." Finneas also produces Eilish's songs.

When the Grammy award winner isn't working with his Grammy award-winning sister, he's doing his own thing. If you're a fan of Selena Gomez's "Lose You to Love Me," that's partly because of Finneas. thank."He just added that final touch, and it just really made a difference from the second chorus into what he did in the bridge," Gomex told Sirius XM via Insider). Want to check out his solo work? The singer and songwriter released his first album Blood Harmony in 2019.

Do you play Justin Bieber's "Lonely," on repeat? Do you have Demi Lovato's "Commander in Chief" on all of your playlists? Is Camila Cabello's "Used to This" your jam? Thank Finneas Baird O'Connell for producing those songs (via Insider).

Unlike his younger sister, the singer-songwriter moved out of his parent's house. He's had his own place since 2019 (via Billboard). That was around the time that Finneas started headlining shows, himself. At his second-ever self-headlined show, in New York, he sold out. Fame has been a mixed-blessing for Finneas. It's affected his relationships with his sister. "Not our sibling dynamic," he clarified to Vogue, "but it's changed our ability to go places together, which is too bad. I wish that weren't the case. We just love each other and are honest with each other, and we speak the same creative language. There's no other person I like working with as much as my sister."

Before deciding on music, Billie Eilish's best friend and big brother might have been an actor. He's worked alongside Cameron Diaz in Bad Teacher, although you might recognize him better from his appearances in Modern Family. "Working on TV shows was fun, but I felt crazy pressured and stressed," he told Billboard. Sorry, not sorry, that he's stuck to music.
