Britney Spears, Kate Hudson and Victoria Beckham are among a host of stars who have been famously Photoshopped to 'perfection'.

In a set of fan-made pictures to celebrate the release of new single Womanizer, Britney is almost unrecognisable thanks her tiny waist and super-long legs.

Jessica Simpson's womanly waist was also airbrushed to impossibly svelt proportions on a recent cover of Elle magazine.

Of course, retouching can work the other way too - Posh had her bony behind plumped up for a perfume ad and Kate Hudson gained a cleavage for the Fool's Gold movie poster.

With every bulge or wrinkle being digitally banished to create a younger, thinner, sexier look, we've hightlighted some of the most dramatic examples.
