Kitty Brucknell has annoyed both Louis Walsh and Tulisa by saying the N-Dubz star isn't as good as former X Factor judge Cheryl Cole! Louis apparently overheard Kitty bitching about best pal Tulisa, and gave the kooky performer some harsh words of advice.
Despite strongly supporting Kitty on the show, and singing her praises time and time again, Louis supposedly threatened to cut his ties with Kitty if she didn’t calm her ego down.
A source told Closer magazine: "Kitty was overheard bragging to rival contestants: 'More people tune in to see me than Tulisa. It's me they're all talking about - she's nowhere near Cheryl Cole's league'.
"Kitty was then given a furious dressing down by Louis when he heard she'd been bad-mouthing Tulisa."
The source explained: "He told her she was out of control, out of her depth and if she ever spoke badly about Tulisa or anyone else again he wouldn't work with her.
"He told she's on her last chance. Kitty just shrugged her shoulders. It's like she has no respect for them at all."
