Cheryl Fernandez-Versini's future as an X Factor judge may not be looking too rosy. The singer's spot on the panel looks like it could be in jeopardy as it emerged Simon Cowell is auditioning for a new female judge. The news comes after X Factor bosses vow to do whatever is needed to boost the shows dwindling ratings and to beat the main competition, Strictly Come Dancing. So far X Factor presenter Dermot O'Leary has left the show and there is a rumor that pop veteran Robbie Williams could be replacing long standing judge Louis Walsh.
