Tulisa Contostavlos heaps praise on Nicole Scherzinger

Tulisa Contostavlos is adamant there will be no cat fights with new X Factor judge Nicole Scherzinger, because the former Pussycat Dolls superstar is such a softie.

The American superstar has replaced Kelly Rowland on this year's panel, after falling to hold onto her seat on the US version of the series.

Contostavlos famously had several bust-ups with Rowland last year after accusing her contestant Misha B of bullying rival acts.

But the N-Dubz singer insists there will be no fall-out this season - because Scherzinger is such a nice girl.

She tells The Sun, "Nicole's wicked. Everyone keeps asking me, 'Can you expect any brawls this year, or dramas?'

"But Nicole is just such a sweetie, she's too nice. It will never happen. I even tell her, 'Come on Nicole, be a meanie, toughen up!' But that's just who she is. She's a lovely, girl-next-door, down-to-earth person who is extremely talented. And she knows her stuff. I doubt you'll see any brawls from us this year."
