A childhood Halloween photograph published Tuesday by TMZ.com shows a young girl in fairy wings — an image the outlet identifies as a young Olivia O'Brien, who grew up in Thousand Oaks, California, before becoming a professional singer.
According to TMZ.com, the future performer was teaching herself piano and guitar during those early years in the Ventura County community. The outlet reports that she began singing at just 7 years old.
O'Brien is likely best known for her featured appearance on Gnash's "I Hate U, I Love U," which peaked at number 10 on the Billboard Hot 100, according to TMZ.com.
The feature, published October 27, 2026, at 12:01 AM PDT, is part of the outlet's "Guess Who" series, which invites readers to identify a public figure from a childhood image.
For Thousand Oaks readers, the item offers a local connection to a performer whose career began with self-taught instrumental practice and childhood singing in the community.
