Billie’s parents are both actors – her mum Maggie Baird was an actress starring in the likes of Another World, Picket Fences, and X Files, before turning to voice work. Billie Eilish has been interested in music since she was 8. Although the teen sensation didn’t plan to become professional, she got great training as a musician – mostly due to her father… Wolfgang Van Halen, who also plays bass in his dad's band. That's the message straight from Eddie Van Halen's son. He is the husband of  Maggie Baird and father of  Finneas O'Connell and Billie Eilish.

Patrick Mead O'Connell (born July 7th, 1957) is an American actor. Dad Patrick Baird … Don't shame people who don't know Van Halen. Billie Eilish will co-host an Apple Music radio program with her father, Patrick O'Connell, called "me & dad radio." Billie Eilish launches a new Apple Music show Friday, "Me & Dad Radio," with her father, Patrick O'Connell, sharing favorite songs.
