Rihanna To Guest Judge On X-Factor

The 51-year-old looks to be pulling out all the stops to ensure the American version of the talent competition is a hit.



On the show, judges bring on guests to help them decide which hopefuls to mentor - and Antonio 'L.A.' Reid, who signed Rhi Rhi, 23, in 2005, will bring her on board to help him decide.

According to US website TMZ.com, the Man Down hitmaker enjoyed partaking in the UK finale last year, and it looks as if Cowell feels the same way. The new X Factor is due to launch in the US on September 21.
