The name chosen by the public was announced: 'Fifth Harmony'. Cowell decided to send 1432 through to the Top 12 and announced that they would be renamed via the viewers online.

During the first live results show on Novemperformed 'Skyscraper' by Demi Lovato in a sing-off with three-piece girl group Sister C. Cowell and Reid were critical of the new name, and Cowell suggested that the group be renamed again. Thereafter, Lylas changed their name to 1432 (a colloquial term for I Love You Too), which was announced on the first live show on October 31, during which 1432 performed 'We Are Never Ever Getting Back Together' by Taylor Swift. Initially, the group's name was 'Lylas' (an 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. Afterward, Marc Anthony called the performance 'unbelievable' with Cowell sharing similar sentiments saying that they were 'clearly one great group'. For their qualifying song at the 'judges' houses', and their first song as a group, Fifth Harmony sang an acoustic version of 'Impossible'. They failed to progress to the 'Teens' category, with Brooke failing to progress in the 'Young Adults' category and were put together to form a five-piece girl group at The Fillmore, in Miami, Florida on July 27, thus qualifying for the 'Groups' category. Demi Lovato, one of the judges, along with Simon Cowell helped form the group.

In December 2012, Ally Brooke, Camila Cabello, Normani Kordei, Dinah Jane and Lauren Jauregui auditioned as solo contestants on the second season of the American televised singing competition The X Factor.
