X Factor 2012 judges: Tulisa advises Nicole Scherzinger to 'toughen up'!

Nicole Scherzinger (X Factor 2012)Tulisa Contostavlos is reportedly trying to 'toughen up' her fellow The X Factor 2012 judge Nicole Scherzinger!

The Sun claims the N-Dubz star wants to see more attitude from the former Pussycat Doll, who's usually more shy and quiet than bold and brash.

She said: "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."

Nicole is replacing Kelly Rowland on the panel this year after she departed the American version of the show.
