Little Mix were put together on, and went on to win, the 2011 series of ITV's The X Factor under the mentorship of judge Tulisa. Originally called Rhythmix and featuring Jesy Nelson, Little Mix comprise Perrie Edwards, Leigh-Anne Pinnock and Jade Thirlwall. In 2016 they became the X Factor winners with the most UK Number 1 singles as Shout Out To My Ex landed them a fourth chart topper, they later added a fifth Number 1 to their CV when Sweet Melody hit the top spot in January 2021 shortly after the departure of Jesy. Little Mix's UK Number 1 songs include Cannonball, Wings, Black Magic, Shout Out To My Ex and Sweet Melody. As well as being the first ever group to win The X Factor, ten years later Little Mix also made BRIT Awards history in May 2021 when they became the first ever girl group to win Best British Group.
