Fifth Harmony won MTV's Artist To Watch award at the 2014 MTV Video Music Awards. In 2014, Fifth Harmony was labeled as the #1 most 'Influential' X Factor USA contestant of all-time by FoxWeekly. Their debut EP, "Better Together" was released in 2013 with a first week position of No. 6 on the Billboard 200. Their debut studio album, "Reflection" will be released in January 2015.

Fifth Harmony is composed of five singers who all successfully auditioned as soloists on The X Factor, but failed to progress individually to the Judges' Houses stage of the competition. They were later formed as a group at the end of bootcamp by Simon Cowell, thus qualifying for the "Groups" category. Originally, the group's name was "LYLAS" (acronym for Love You Like a Sister), but another group called "The Lylas" (which consists of four of Bruno Mars' sisters) claimed that the show stole their name. Thereafter, LYLAS changed their name to "1432" (which stands for I Love You Too), which was announced on the first live show on October 31, 2012, during which 1432 performed "We Are Never Ever Getting Back Together" by Taylor Swift. Simon Cowell and L.A. Reid were critical of the new name, and Cowell suggested that the group be renamed again. During the first live results show on November 1, 2012, 1432 performed "Skyscraper" by Demi Lovato in a sing-off with Sister C. Cowell decided to send 1432 through to the Top 12 and he announced that they would be renamed by the viewers online. The name chosen by the public was announced: "Fifth Harmony".
