Rihanna Makes Debut As USA X Factor Judge

Rihanna has joined the X Factor USA as a judge in the houses stage of the show.

The singer joined LA Reid at the houses stage of the competition, whilst Mariah Carey joined Simon Cowell as a guest judge.

Speaking in the episode, which airs tonight (October 13), Rihanna says:'''I don’t know who’s more competitive between L.A and Simon. They are both very stubborn individuals.''

Adding: 'Simon is.. very raw. Let’s put it that way. With the way that he approaches critique. But it’s very honest. You have to listen to everything he says, no matter how nasty it might sound.'

Earlier this year Cheryl Cole, who was set to appear as a judge on the US version of the X Factor was replaced by Pussycat Dolls singer Nicole Scherzinger.

The Girls Aloud star was sacked from the programme reportedly amid concerns from US TV bosses over her Newcastle accent.
