'X Factor' Hopefuls Get Their First Taste Of The High Life At Judges' Houses (PICTURES)

The remaining 24 'X Factor' acts have had their first taste of the high life as they are seen being put through their paces at the judges' houses stage.

The contestants who have made it this far - six acts for each of the ITV show's judges - jetted off to spend time with their mentors to refine their performances, but half their number face the prospect of being sent home.
