X Factor 2012 judges London

X Factor stars JLS stopped by to the X Factor 2012 auditions today, helping out Xtra Factor host Caroline Flack.

The telly presenter is on her own for the audition stage of this year's show, with her 'TV husband' Olly Murs in the US on tour with One Direction.

Fortunately, she's found herself four hunky replacements for the day in the form of JLS.

Meanwhile Rita Ora returned as a guest judge on the show, joining Gary Barlow, Tulisa and Louis Walsh at London's O2 Arena.
