Cheryl ColeCheryl Cole leaving the X Factor studios this weekendCheryl Cole has reached number one in the charts...

But something is troubling her.

The X Factor judge has revealed she's missing her Girls Aloud bandmates.

Cheryl, whose solo single Fight For This Love hit the top spot yesterday, said: "It's a little bit lonely,"

Speaking of branching out from her bandmates Kimberley Walsh, Nicola Roberts, Nadine Coyle and Sarah Harding, Cheryl told Attitude magazine: "It is weird. It's a little bit lonely.

"I find myself either glad that there aren't four other opinions at times or hating the fact that there's not.

"I can't give the 'Cheryl' look where you look at one of them across the room and they answer the question or they sense that you're fed up so they do it anyway."

She admitted that there is more pressure on her during promotion now that she is on her own: "You have to be completely on the ball in every aspect. You haven't got any shielding.

"It's been up and down really."
