Little Mix are a British girl group that formed on the eighth series of The X Factor. They are the first group and the only girl group to win the original UK series. The lineup consists of Leigh-Anne Pinnock, Jade Thirlwall, Perrie Edwards, and previously Jesy Nelson until her departure in 2020. Regarded as the show's most successful winning act, their success led to a girl band renaissance in the UK. Little Mix's vocals and harmonies have garnered critical acclaim and the group have been ranked as one of the best vocal girl groups. They were often dubbed, by some media, as the "biggest girl group in the world", before going on a hiatus in 2022, allowing its members to pursue solo projects.
