Cheryl Cole has seemingly been dropping hints that she may return to The X Factor this year. The 30-year-old singer, who was a judge on the popular reality show between 2008 and 2010, posted a 'Throwback Thursday' image of herself sitting next to Simon Cowell on the judging panel. The star sued The X Factor USA for £1.4million and had a famous falling out with the show's originator Cowell.
