Rumours have been rumbling for days about diva behaviour on the X Factor set - now Cher Lloyd has confirmed that she had a 'meltdown' at show stylists about her clothes.

She confessed that she had thrown a strop because she was unhappy about what show stylists wanted her to wear for Saturday night's show.

Talking in this week's X magazine, she said: 'I had a bit of a meltdown earlier in the week. But I just couldn't go on stage in something I felt uncomfortable in.'

The 17-year-old went onstage instead in her own clothes, and shoes lent to her by her mentor Cheryl Cole.

She joked: 'It's a good thing Louis isn't my mentor, or I'd have been wearing his shoes on TV.'

She took to the stage eventually in black and white patterned baggy trousers, a cheap-looking T-shirt that said 'Bite Me' on the front, black leather jacket and heavy gold chains.

The tiny star meanwhile showed off her questionable taste today wearing an unflattering oversized cardigan and bizarre knitted over the knee socks which did up with pompoms, that she wore over woollen tights.

Perhaps she was celebrating National Wool Week which is taking place at the moment...

Whatever the reason, Cher was also wearing zipped wedge mules and her trademark heavy make-up and backcombed hair when she arrived at the X Factor studios in north London for rehearsals.

Meanwhile, Robbie Williams has revealed his fears for Cher after she almost collapsed backstage after Sunday's results show.

Talking to X Magazine he said: 'I wasn't as fragile as she is when I was 16. I want to give her a call but I don't know if I can help.'

'She's obviously got it. But she'd have done well not to get through and have another year to come to terms with her personal life.'

Judge Cheryl Cole caused huge controversy after choosing Katie Waissel and Cher - despite poor performances at the previous stage of the contest - at the expense of Gamu, who is facing deportation to Zimbabwe.

Katie's mother has said she is being bullied and has spoken of her fears that her daughter will be pushed off the show.

The 24-year-old also received flak after getting through to the live finals at the expense of Gamu.

She was surrounded by more controversy when judges decided to save the quirky singer from the boot instead of boyband FYD.

Last year, some of the show's fans turned on talented singer Danyl Johnson, and Katie's mother Diana said she did not want the same thing happening to her daughter.

She said: 'There seems to be this thing that Katie has got someone else's place. I don't know why everyone is blaming her. It happened last year in a way to Danyl and he was a good singer and he was a nice guy and he was pushed out.'
