The daughter of saxophonist Warren Hill and his wife, singer turned music producer Tamara Van Cleef, Olivia grew up surrounded by music. Her father even let her come up onstage and sing her favorite song, "Somewhere Over The Rainbow", when she was just a toddler. At age 14, Olivia tried out for season 8 of America's Got Talent but was eliminated in the Vegas Round. She also has a YouTube channel where she has posted videos of herself singing cover songs as well as original material.

She advanced passed Hollywood's Lines of Ten, Group Round, and performed "Genie in a Bottle" by Christina Aguilera for her Hollywood Solo round. She then advanced to Showcase week where she performed "Love Somebody" by Maroon 5 and advanced to the Top 24. During the Top 24, she performed "Confident" by Demi Lovato and performed a duet with David Cook singing his original song "Light On". Afterwards, she advanced to the Top 14 where she received a designated spot by the judges in Season 15's Top 10 and didn't have to perform for America's Vote. During the Top 10 she performed "Unconditionally" by Katy Perry but was eliminated in a double elimination with fellow contestant Gianna Isabella finishing in 9th/10th place.
