Louis Walsh is predicting new X Factor judges Kelly Rowland and Tulisa Contostavlos will clash ‘big time’ on the show.

The veteran panel member revealed to Closer magazine the Destiny’s Child star and the N-Dubz frontwoman have already disagreed during The X Factor auditions over acts, and he thinks there will be more to come.

Louis said: “Kelly and Tulisa have had disagreements on camera over different acts. It’s brilliant because they aren’t being fake and pretending to agree about everything and being all nicey nicey. It’s so refreshing.

“I can definitely see them clashing big time when the live shows start. They’re both very determined and strong in their views, which is exactly what The X Factor needed.”

The Westlife manager also revealed that Take That star Gary Barlow is taking on Simon Cowell’s ‘Mr Nasty’ role.

He said: “Gary’s going to surprise so many people with how little nonsense he takes.

“You have to remember, this was a guy who started singing in bingo halls and made it to be one of the biggest pop stars on the planet, so he knows all about hard work. He can’t be bluffed or fooled by anyone.”

Louis admitted he missed having Cheryl Cole on the judging panel. He said: “I miss her drama. There was always some drama around when Cheryl was at the show – and I mean that in the nicest way! There’d be something happening to her puppy or some kind of wardrobe thing going on.”

But he thinks the Girls Aloud star did the right thing leaving US X Factor.

He said: “I actually think Cheryl didn’t really want the show. Her heart wasn’t in it and she never felt comfortable there, in my opinion.”
