X Factor judge Cheryl Cole has admitted that she has one very dirty habit.

The Girls Aloud star smokes at least five cigarettes a day and has confessed that despite all the health risks, she just can’t give them up.

In an interview with Metro, Cole honestly explained:

‘I miss smoking when I stop.’

‘It’s not cool to say so but I do.’

Cheryl – who has been tipped to join the new American X Factor judging panel later this year – recently talked about her vice with Piers Morgan on his ‘Life Stories’ series.

‘I probably smoke about 5 a day, not many – but probably 20 today,’ she said.

Of course, she’s not the only star who craves a fag, her boss and mentor Simon Cowell is a well known lover of menthol cigarettes and the pair are often spotted enjoying smoke breaks together when filming their ITV show.
