Little Mix
Little Mix entered the competition as four separate acts in the "Girls" category. They were put together as a group by the judges later on in the competition. They were originally called Rhythmix. Their mentor in the competition was Tulisa Contostavlos, an R&B singer and songwriter best known as part of hip hop trio N-Dubz. Little Mix won the competition in December 2011, beating Marcus Collins and Amelia Lily in the final.
