"Robbie Williams and Gwen Stefani are reportedly being lined up as guest judges on The X Factor. Filmed auditions start in Liverpool on Wednesday but bosses are still searching for a permanent replacement for Kelly Rowland after Dannii Minogue rejected a \u00A31m offer to return.   &amp;gt; Katy Perry, Lily Allen, Noel Gallagher: X Factor replacements in pics Alicia Keys will join Williams, Stefani and Rod Stewart as a guest judge, The Sun reports. Williams often performs with the X Factor contestants and last year helped Take That bandmate Gary Barlow at Judges&amp;#039; Houses, emerging in a Sinitta-style leaf outfit. Meanwhile, Katy Perry, Rihanna and Nicole Scherzinger have all turned down the chance to be guest judges, according to the Daily Star Sunday.   &amp;quot;At this rate the fourth judge may not be signed until much later in the series,&amp;quot; a source said. &amp;quot;Dannii turning them down was a massive blow because as far as ITV1 and The X Factor were concerned it was a done deal. &amp;quot;The back-up plan is to have a host of guest performers take part in the regional auditions and possible Boot Camp before revealing a permanent name at the Judges&amp;#039; Houses in August. Everyone involved knows how important the judges are to the success of the show. &amp;quot;Numerous high-profile singers have come forward wanting the job. But bosses fear they aren&amp;#039;t big enough names to wow viewers. So it&amp;#039;s now panic stations to make sure they can sign up a big enough name in time.&amp;quot; While a permanent judge is unlikely to be found before Boot Camp, former Spice Girls Geri Halliwell and Mel B, The Saturdays singers Frankie Sandford and Rochelle Wiseman and Britain&amp;#039;s Got Talent judge Alesha Dixon are all said to be in the frame. Barlow, Louis Walsh and Tulisa Contostavlos will return to The X Factor, as well as host Dermot O&amp;#039;Leary.
