They reached the live shows section and were mentored by Tulisa Contostavlos. During the first live show on 8 October 2011, Rhythmix performed Super Bass by American recording artist Nicki Minaj. Their rendition was praised by the judges with Gary Barlow calling them the "best girl band that's ever been on The X Factor. " On 26 October 2011, the band announced that they would change their name following a dispute with Rhythmix, a Brighton-based children's music charity of the same name, after the programme tried to trademark "Rhythmix". A spokesman for The X Factor said, "At the request of the charity Rhythmix, the members of the girl group Rhythmix have decided to change their name, a decision which has the support of Syco and TalkbackTHAMES. " It was reported that the group decided to make the change, with no legal requirement to do so, to avoid any difficulties for the charity. On 28 October 2011, it was announced that the group's new name would be "Little Mix".
