Cheryl Cole in Series Five?

It has been rumoured that, popular singer and X Factor judge Cheryl Cole, could be offered a part in an upcoming episode of Doctor Who. Although this is highly unlikely because of her busy schedule, an 'insider' said, "If she can find the time, a part will be written for her." In response to this, the BBC have said, "The BBC will not be commenting on casting or storyline speculation for the new series of Doctor Who."

I'm not sure what to think of this... I do like her but can she really act? Will she really say way aye to the offer? (Yeah, that was bad, I know. Never mind.)
