Now Coleen is the Diet Coke queen

Coleen McLoughlin is to become the face of Diet Coke in a six-figure deal which follows her fiance Wayne Rooney's signing as the face of Coke Zero, a no-sugar version of original Coca-Cola.

Coleen, 20, and Rooney, 21, will appear on billboards together before Christmas.

"This is being seen as a major coup for Coke as it is the first company to get Wayne and Coleen to star in an advert together," said a source on the campaign.

"Until now they have always wanted to be seen as separate acquisitions."

Coleen's deal is to be announced officially later this month. Meanwhile, Rooney's £1million one-year deal is set for renewal.

The source added: "Because he has been so successful his contract is about to be made long term.

"She is young, pretty - and she happens to love Diet Coke. The idea of having Wayne and Coleen as the King and Queen of Coke was irresistible."

Just months after Asda signed up the Manchester United striker to advertise its wares, Coleen was signed as the face of its George fashion label and Must Have range in a £1.5million deal.

And soon after Nike signed Rooney, Coleen was paid £1.5million to promote the Nike C range for women.
