Little Mix talk to Newsround

X Factor is back, but what is it really like to be on the show? Last year's winners Little Mix were the first girl band ever to win the competition.

They were put together by the judges at boot camp and went on to win.

It's a year since the group got together and their debut single has just been released.

Leigh-Anne, Perrie, Jessy and Jade have been telling Nel all about X Factor and what they've been up to since they won.
