Kate Winslet's dramatic airbrush transformation

Oscar-winning actress Kate Winslet has undergone a striking transformation for the newest cover of US Vogue.

No, she hasn't had cosmetic surgery. The stunning star has fallen victim to severe airbrushing, which has caused her skin to appear eerily smooth, her eyes unnaturally bright and the lines of her face strangely softened.

But Kate's high impact Photoshop transmogrification has not just involved the typical wrinkle-smoothing, blemish-removing, hair-shine-enhancing effects.

Kate's recognisable square jaw has been reshaped to appear soft and less angular, and one of the moles on her right cheek has been completely removed.

While the Titanic star - who is pregnant with her third child - is yet to comment on the dramatic cover, her reaction may not be so hard to predict.

The star has previously spoken out against extreme Photoshopping after she appeared on the cover of GQ magazine.

She said of her noticeably slimmer and elongated legs in the cover photo in 2003:

"The retouching is excessive. I do not look like that and more importantly, I don't desire to look like that.

"I actually have a Polaroid that the photographer gave me on the day of the shoot...

"I can tell you they've reduced the size of my legs by about a third. For my money it looks pretty good the way it was taken."

The star also successfully sued UK's Daily Mail in 2009 for 'offensive' claims that she had lied about her exercise regimen, saying in an official statement afterwards that she felt she had 'a responsibility' to request an apology to show her 'commitment to the views [she has] always expressed about body issues, including diet and exercise'.

"I strongly believe that women should be encouraged to accept themselves as they are, so to suggest that I was lying was an unacceptable accusation of hypocrisy," she said.
