It has been admired and revered all over the world. Now it appears Pippa Middleton's shapely behind is inspiring a legion of imitators too.
Cosmetic surgeons in the U.S. are reporting a huge rise in the number of women wanting buttock operations so that they look like her.
Among those to have gone under the knife are Christina Valdez, from Miami.
In pursuit of Pippa: Christina Valdez had surgery to get a derrière like the Duchess of Cambridge's sister
The single mother, 28, described how she was inspired to emulate Miss Middleton, 27, at the Royal Wedding in April.
She told Good Morning America: 'She's got a nice rump that's not too big. Her frame just looked incredible in that dress.
'I was like, "That's it. This is it, I just have to look like her. If she can look petite and great and still have a nice backside to her, so can I."'
Ms Valdez's surgeon says one in six of those who go under the knife are specifically asking for a 'Pippa butt lift'.

He says that 80 per cent of his patients want buttock operations, and of these, 20 per cent use Pippa as their 'rear idol' in consultations.
'In that wedding gown, she created a stir,' he said. 'People want those dimensions. She's just gorgeous.'
Pippa's posterior became an overnight sensation thanks to her figure-hugging Alexander McQueen gown at her sister's wedding to Prince William.

But experts have warned that buttock operations should not be undertaken lightly and can be fatal if carried out improperly.
For those undergoing any buttock procedure there are two main options: implants or fat redistribution.
Injections of synthetic material are also possible, although they are often unregulated and could be dangerous.

The student suffered heart attack after the £1,200 treatment, which was a top-up to similar jabs
In Britain such a procedure takes place under general anaesthetic and would cost around £3,000.
The patient will probably be allowed to go home the same day but they would have to wear protective underwear for several weeks afterwards.
They would also have to avoid sleeping on their back, driving in a car and bending over for up to six weeks in case it interfered with the recovery.
