X Factor USA kicked off auditions in Texas yesterday, and following concerns Britney Spears wasn't well enough to handle her judge role (due to her bitten fingernails) rumours claimed she walked off set.

Britney Spears was said to have walked off X Factor USA after a contestant gave a bad rendition of her song 'Hold It Against Me', TMZ reported.
