Olivia O'Brien (born November 26, 1999) is a singer-songwriter from Napa, CA and currently living in Los Angeles, CA. She first grew to prominence releasing covers on her SoundCloud.
One song, “hate u love u,” was noticed by gnash, who remastered the song, included O'Brien’s chorus and one verse, added his own verse, and re-released the song under the title “i hate u i love u.” That song blew up, reaching the top 10 of the Billboard Hot 100 and topping the Australian charts.
She is the cousin of Devon Carlson and Sydney Carlson.
