Washington, Mar 28 : Welsh singer-songwriter Duffy has vowed that she will never endorse another product again, after her TV commercial for Diet Coke was criticised by U. K. campaigners over road safety fears.
Duffy, 24, who is currently promoting the low-calorie beverage in a European advertising campaign, is seen riding a bicycle through dark streets without a helmet or reflective gear.
The singer was criticised for the promo by officials at the Royal Society for the Prevention of Accidents, after it debuted last month.
