Rita Ora has accused Louis Walsh of being "a little burnt" after being overlooked for this year's 'X Factor'.

The 24-year-old singer has come to the defence of Nick Grimshaw, whose judging performances have been criticised by the Irish music mogul, suggesting Louis' recent remarks are the result of jealousy.

Rita said, sarcastically: "I think someone's just a little bit burnt they lost their chair. It's OK Louis, I'll rub your feet you if you want. It's OK."

Rita also defended Nick's judging talents, saying he has "great ears" for pop music.

She told the Sunday Mirror newspaper: "Let me tell you something - he's a hard worker and he has great taste and great ears.

"He may not be able to physically stand on stage and sing a song but you don't need to. He's one of the important hands that plays the songs that you guys get introduced to on the radio."

By contrast, Louis said last month that fans of the show may prefer to see him replace Nick.

He said: "I'm not sure about Grimshaw. I haven't seen much of him. People don't like change and I think they miss Dermot [O'Leary] and maybe some people miss me."
