This weekend sees the shows come head to head for the first time this year, with both programmes having made changes to their line-ups. ITV's X Factor have welcomed back a very familiar face in Cheryl Fernandez-Versini, returning to the judging panel for the first time since 2010, along with music mogul Simon Cowell. The BBC can boast more big names on Strictly with their celebrity format, with the likes of Pixie Lott and Frankie from the Saturdays taking to the dancefloor.
