Per reports, the 26-year-old and his sister started making music together as children in the Los Angeles Highland Park area, where they were raised by their parents, Maggie Baird and Patrick O'Connell. Baird and O'Connell were working actors who homeschooled their kids, with Finneas describing the family as "a very crunchy, sort of hippie-dippy family."

His father also mentioned in an interview, "We have never put any emphasis on getting a job and making a living. If we modeled anything, it was being broke and artsy."

Before gaining recognition in the music industry, the Academy Awards winner starred in a few productions between 2013 to 2015, including cameos on "Modern Family," the final season of "Glee" as Allistair, and "Life Inside Out" as Shane.

He said of his role in "Glee," "I felt like I'm part of the end of this seminal thing. It's so funny to be doing your fourth episode of a show, and everybody's weeping, and it's like, their 130th episode."

About four years later, following Finneas' contribution to Billie's first album, he released his debut solo EP "Blood Harmony," inspired by his bond with his sister. He is presently in a relationship with YouTube star and fashion influencer Claudia Sulewski who has quite the following on Instagram and YouTube and whom Finneas wrote the song "Claudia" for on the first day they met.
