Cheryl Cole's discomfort was clear to see at last week's Fox Upfront party, where Simon Cowell gave Paula Abdul - who worked with him on American Idol - his undivided attention.

Now reportedly 'booted off' the US X Factor, Cheryl, 27, is thinking hard about her life and what she really wants.

And she doesn't intend to end up like Paula, childless at 48 and with 2 divorces behind her.

‘When Cheryl was married to Ashley she thought she'd have kids by now.

'Seeing Paula reminds her how easy it is to spend so much time working that 
you neglect your personal life,' says Now's source.

Meanwhile Paula - who's 21 years older than Cheryl - is going to great lengths to retain her queen bee status 
by looking youthful.

The singer - who's always denied having plastic surgery - has been going for non-surgical Titan skin-tightening sessions to turn the clock back.

Representatives for Cheryl and The X Factor have yet to comment.
