Watch our Finalists tear it up backstage as they get ready to take to the stage for Rock Week. Oh, and there are some AWESOME celeb appearances too!
We have just caught up with Jade, Jesy, Leigh-Anne and Perrie, who have revealed their new name is Little Mix!
The girls said: "We're really excited to announce that as of now our new name is Little Mix!
"We came up with the name with Tulisa and we love it - we hope our Little Mixers like it too!"
Little Mix went on to explain: "When we came up with the name Rhythmix, we had no idea that there was a charity with the same name. We decided to change our name to Little Mix as we do not want to cause any problems for the charity, and we're happy that this has now been resolved. We're the same girls as we've always been and we want to thank all of our fans for their continued support of us.
"We came up with some ideas for our new name which we discussed with Tulisa and she had some ideas too. We all agreed on Little Mix as it just felt right. We're so excited to perform on Saturday and hope everyone is impressed with what we do."
