N-Dubz' Tulisa Contostavlos 'Worried About' Cheryl Cole Over X Factor Saga

N-Dubz star Tulisa Contostavlos has said she was concerned Cheryl Cole may get her old job back on The X Factor.

Contostavlos was revealed as Cole's UK replacement last month, but when the Girls Aloud star was sacked from the US version it was rumoured she may return to the original format.

"When it was all going on, I tried to keep my head down but, yes, I was a little nervous she might get her old job – or my new one – back,” Contostavlos told the Daily Mirror.

“Cheryl sent me some flowers on my first day, which was a pretty amazing gesture and totally unexpected.”

She added: “To be going through all that she is, well, that's a very kind, thoughtful gesture."

Contostavlos is joined on the judging panel by Take That's Gary Barlow, Kelly Rowland and Louis Walsh.
