List of The X Factor finalists (U.S. season 2) Fifth Harmony (formerly LYLAS and later 1432) is a four-piece girl group. Ranging from ages between 15 and 23, the four members from oldest to youngest are Allyson "Ally" Brooke Hernandez (born on July 7, 1993 in San Antonio); Normani Kordei Hamilton born May 31, 1996 (born on May 31, 1996 in Atlanta, Georgia); Lauren Michelle Jauregui (born on June 27, 1996) and Dinah Jane Hansen (born on June 22, 1997 in Santa Ana, California) and Camila Cabello (who later left the group in Dec 2016 to launch a solo career). Brooke, Hamilton, Jauregui, Hansen, and Cabello all applied as solo contestants, but failed to qualify for the Teens (or Young Adults) category. After a discussion from all four judges, they were put together to form the group Fifth Harmony, thus qualifying them for the Groups category.
