Cheryl Cole `crying herself to sleep`

The 27-year-old singer had moved to Los Angeles and is still waiting to find out if she will be given a slot as a judge on the X-Factor.

Her brother Andrew was jailed last week for helping to plot an armed robbery, and a source told Now magazine how that is just the start of her problems.

'On top of that she‚'s had to cope with a slap in the face from Elton [John] - who called her music 'crap',' said the insider.

'Add to that Simon [Cowell] being too focused on his big deal with the US X Factor producers Fox to take her calls, she's feeling completely used and abandoned.'

Now mum Joan has had to fly out to be with her daughter.

'Cheryl, who's been crying herself to sleep, told Joan if she couldn't get there she'd be forced to call Ashley,' added the insider.

'What her mum doesn't realise is she's already in constant touch with her ex-husband as he's really the only one who seems to understand what she's going through.'

A source close to her official camp insisted that Cheryl is not having a meltdown or feeling ill and is busy working.
