"Everyone keeps asking me, 'Can you expect any brawls this year, or dramas?' But Nicole is just such a sweetie," Contostavlos told The Sun. "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."
Contostavlos recently hit back at "bulls**t" reports of a feud with Scherzinger on Twitter, telling the press to "p*ss off" and stating: "Ur always guna try and make a headline cus uve got nothin good 2 write about."
Scherzinger's emotions got the better of her during last week's X Factor Boot Camp in Liverpool when she was reduced to ! tears by a contestant's heartfelt performance.
