Drink companies in Japan as well as the USA and UK are looking to snap up jazz songstress Amy Winehouse to front advertising campaigns, on TV, billboards and print.

The north London smoky-voiced singer is said to be on a list of celebrities set to be courted by three global drink firms.

According to an insider, Winehouse could make up to £2m if she chooses to endorse a drink company and its alcohol range.

“Amy’s distinctive voice stands out and the advertising departments of these companies are looking for famous people with something distinctive about them,” said a source. “Of course, it will be rather ironic is any of them choose Rehab as a song to be promoted with a drink.”

A Winehouse spokesman said: “Amy’s management are being asked all the time if she would consider endorsing products. It’s still early days as to what, if anything, she will be happy to endorse.”
