Cabello auditioned for The X Factor in North Carolina. She first auditioned for the producers' part of the audition and got the call back saying that she will audition for the judges as an alternative, meaning that if after the show, if they were to have time, she would be able to audition. After her audition, she got a 'yes' from all four judges. After elimination during bootcamp, Cabello was called back to the stage along with four other female contestants to form the girl group that would later become known as Fifth Harmony.
In November 2015 Cabello released a duet with Canadian singer Shawn Mendes titled "I Know What You Did Last Summer". The song charted at number 20 in the US and 18 in Canada. It was certified platinum by the Recording Industry Association of America (RIAA). In October 2016 Cabello will release a joint single with American rapper Machine Gun Kelly called "Bad Things".
