Britain's Duchess Catherine lost weight in the run up to her wedding to Prince William because the planning was an "ordeal".

Handbag designer Anya Hindmarch has revealed the much-discussed weight loss of the 29-year-old beauty prior to her April 29 nuptials was not because she was being unhealthy, but was simple struggling to cope with the pressure of the engagement.

I hope she doesn't become too much of a fashion icon because it would be exhausting for her.

She said: "I know her a bit and she's a naturally healthy girl. She does a lot of exercise and no wonder she lost weight around the wedding - it's quite an ordeal to go through.

"I hope she doesn't become too much of a fashion icon because it would be exhausting for her."

Duchess Catherine was said to be concerned at her weight loss prior to her wedding at London's Westminster Abbey and was hoping to gain some pounds to retain her curves.

A source said: "Kate's shed weight rushing around planning the wedding.

"But she's worried that she'll lose her curves completely, so she's introducing a lot more carbs into her diet.

"We're not talking huge bowls of spaghetti, but certainly wholemeal toast, oatcakes, porridge and cereals."
