Coleen could pocket £10million if she divorces love Wayne - and DOUBLE her personal fortune.
Top divorce lawyer Ellen Kerr told The Sun: "If the Rooneys are worth around £35million together, it would seem right that Coleen would be awarded around £10million.
"They have a child so she would have to be given enough money to secure his future and she would take a larger share of the house if it was sold.
"Those nights with another woman have cost him dearly."
He could also lose up to £6million in "family man" sponsorship deals.
Finance expert Adam Johns said: "Rooney's philandering will hit him in the wallet. He could lose millions."
