The X Factor has landed the likes of Take That star Robbie Williams to help out the new panel at this year's judges' houses stages. Rapper Tinie Tempah, former X Factor judge Sharon Osbourne and ex-Destiny's Child singer Michelle Williams are also lined up to appear.

According to the Sunday Mirror, show bosses are "desperate" for big names to join the judges in order to make up for the departure of the likes of Cheryl Cole and Simon Cowell from the panel.

Robbie Williams is set to help out fellow Take That star and the new X Factor head judge Gary Barlow pick his final acts in LA this September. UK rapper Tinie will join forces with Tulisa ­Contostavlos in Ibiza while Kelly Rowland will team up with former bandmate Michelle in New York.

Finally - despite reports that JLS and Jedward were battling it out to help Louis Walsh - he'll instead again be joined by pal and former judge Sharon Osbourne.

A show insider told the newspaper: “Because of the judging reshuffle we knew it was important to bag some huge stars. Robbie and Michelle have been in two of the world’s ­biggest bands.”

It was previously reported that N-Dubz star Dappy wanted to help out Tulisa, with the new X Factor judge wanting to take her finalists to her nan's house in Greece!

The X Factor 2011 auditions are now over, with bootcamp starting next week and the judges' houses taking place in September.

The show returns to ITV1 next month.
