What have they done to you, Christina? Slimmed-down Miss Aguilera appears to be anatomically incorrect in new perfume ad

We understand that a degree of Photoshop is a given when it comes to promotional photos, but Christina Aguilera's entire anatomy appears to have been given an overhaul in an ad for her latest fragrance.
The singer, 31, looks significantly thinner in the ad for Royal Desire, in which she is seen in a pale pink strapless dress, with her hair worn short and curled in the style of Marilyn Monroe.
What's more, Jezebel observes, there are several instances in which Miss Aguilera's body has been distorted to the point that it is anatomically incorrect.

Photoshop fail? Christina Aguilera's entire anatomy appears to have been given an overhaul in a bid to slim her down in the ad for her latest fragrance, Royal Desire

Her wrist, to the left of the frame, is perhaps the most obvious. In an likely attempt to slim-down the entire arm, the retoucher, it seems, had trouble with the joint and ended up making it too long and awkwardly bent.
But the apparent anatomical creative licence didn't end there.

 

The other arm has been made to look as though there are two different elbow points, perhaps some clumsy effort to create a shadow, but it is an unfortunate effect.
Nor, the site points out, is the star's face unscathed.

Writer Dodai Stewart comments: 'The chin's been sculpted, but then someone couldn't figure out how to make it look normal where the shoulder meets the neck, so it just turned into a valley of shadows.'
There is just back wall where the waist and the hip on the right should meet - and almost certainly would have done in the original photo.
We're sure that the kneecap and shinbone in her front leg were in alignment originally too - though apparently the retoucher believes they look better with a twist.
