The last time Simon Cowell and Cheryl Cole were both on The X Factor was 2010.
They had an audience of 17.2 million watching Matt Cardle being crowned the winner, but that figure had dropped by 7.5 million for the climax of the 2013 series when Sam Bailey won. Cheryl says this series will be 'fun'.
"I'm very happy and excited to be returning to The X Factor. I'm inspired and ready to find new talent and potential pop stars. It's going to be a fun series."
