Some would say he's the cat that got the cream - but it's low-fat! So there!...

Sir Elton John has signed up to star in a US ad campaign for milk, joining the ranks of celebrities such as Britney Spears, joan Rivers and Jackie Chan.

The ad will feature in the Christmas issue of Time Magazine, with a photograph of Sir Elton wearing a milk moustache alongside the words, ‘I’m still standing. Want strong bones? Drinking enough low-fat milk now can help prevent osteoporosis later.

Sir Elton is reported to have donated his fee to the Elton John AIDS Foundation.
