Dannii's no good to him - happy, stable relationship plus baby. Cheryl's the way to go. I doubt they thought The One would work out so badly, she's known Cowell for years and seemed an ideal choice (still think it was a double bearding operation - an earlier fling with Clay A, please
), but they have as much chemistry together as a brick, a nice little fauxmance with Cheryl ticks all the boxes for both the X Factor and Cheryl breaking the States.
Yeah, smitten or not, it's been a PR disaster, even his own mother now would probably rather see him hitched with Ryan than The One. Time to shave off the beard and get another one.
