The Cuban-American singer Camila Cabello, who has successfully made her way into our hearts and playlists, was just 15-years-old when she got her big break thanks to the American reality show The X Factor. It was judge Simon Cowell who made Camila Cabello join the girl group called the Fifth Harmony, and the rest is history. They went on to become massively popular and gave us hit tracks like Miss Movin' On, Work From Home, Not That Kinda Girl among others.
