Unlike his younger sister, the singer-songwriter moved out of his parent’s house.

He’s had his own place since 2019 (viaBillboard).

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.

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 alongsideCameron DiazinBad Teacher,although you might recognize him better from his appearances inModern Family.

“Working on TV shows was fun, but I felt crazy pressured and stressed,” he toldBillboard.

Sorry, not sorry, that he’s stuck to music.
