Fifth Harmony is an American girl group formed on the second season of the The X Factor USA in July 2012. The group consists of members Ally Brooke, Normani Kordei, Dinah Jane, Camila Cabello, and Lauren Jauregui. They signed a joint deal with Syco Music, owned by Simon Cowell, and Epic Records, L.A. Reid's record label, after finishing in third place on the show. Since then, they have released an EP and a full-length album.

Following their exit from The X Factor, their debut single "Miss Movin' On" was released and was later certified Gold in the US. Their debut EP, Better Together was released in 2013 with a first week position of number six on the US Billboard 200. The following year, they won the Artist to Watch award at the MTV Video Music Awards.

The group released their debut studio album, Reflection in February 2015. It debuted at number five on the Billboard 200, with 80,000 units sold in the first week and was supported by the group's first major headlining tour, the Reflection Tour. The album was supported by the singles "BO$$", "Sledgehammer" and the US Double Platinum "Worth It". The latter also became the group's first top 20 single on the Billboard Hot 100, and reached the top 10 in eight other countries. Fifth Harmony has emerged as the most successful alumni from the X Factor US franchise.
