She has a Famous Family
Her brother is also famous! Finneas Baird O’Connell is an American singer, songwriter, record producer, musician, and actor. You may have seen him on Glee or in the movie Bad Teacher. Billie and her brother collaborate on songwriting as well. Eilish called Finneas her partner in making music and said he produces her music and also performs with her on live shows. She claims that a number of her songs derive from her and Finneas’ experiences.
Maybe that is why people love her music so much – they can feel the passion that goes into the making of it. Bottom line… people love Billie Eilish for her weirdness, wildness, depressiveness, realness and overall bizarre doings.
