Welsh singer is new Coke pop star

Singing sensation Duffy has been signed up to star in a new diet Coke advertising campaign.

The singer from Nefyn in Gwynedd will be seen in the advert across Europe over the next few months.

The ad will feature her as a "strong and sassy" young woman in a series of 30 and 60-second spots for her first ever high profile TV advert.

Duffy is best known for her number one hit Mercy and her album Rockferry, which sold 4.5 million copies.

The singer said she loved the "attitude" of the Diet Coke ad.

"I drink so much of the stuff, they were either going to give me shares in the company or put me in the advert," she added.

Coca-Cola Great Britain marketing director Cathryn Sleight said the singer was a "great embodiment of today's modern female attitudes".

"She has strong appeal with our core female audience and we're confident that this campaign will become just as iconic as previous diet Coke advertising campaigns," she added.
