A native of Maplewood, New Jersey, Miller began performing at a young age and by her teens had garnered voice acting credits in such films as Ice Age 3 and Toy Story 3. In 2012, Miller auditioned for and won a spot on the second season of the Fox singing competition The X Factor with her performance of the Dixie Chicks' "Cowboy Take Me Away." During the show's boot-camp phase, Miller was assigned pop star and judge Britney Spears as her mentor. Although she performed well on The X Factor and drew a large fan following, she ultimately exited in ninth place. After leaving The X Factor, Miller signed a recording deal with Hollywood Records/Syco Music and began work on an album. Her debut EP, the five-song Young Blood, appeared in 2014. In 2015, Miller returned with her full-length debut album, Not an Apology, which featured production from the Suspex, Mike Del Rio, Matt Squire, and others. Included on Not an Apology were the singles "Young Blood" and "Fire N Gold." ~ Matt Collar
