David Beckham has put his wife on a specific diet to "fatten her up".

Victoria Beckham is undertaking a carbohydrate-packed eating plan, in the hope of conceiving a fourth child.

The footballer has taken the advice of nutritional specialists after he became concerned at his wife's weight. They were told that menstruation can be affected by size, and Victoria's current frame could prevent her becoming pregnant again.

A source said: "David knows that Victoria struggles with her body image and thrives on being thin - but he is desperate to see her with a few more curves. David has pleaded with her in the past to put on weight, but now he's finally taken serious action and given her a diet plan to ensure that she fattens up."

'Victoria's agreed to go along with it because she and David are happier than ever at the moment and also because she is desperate to conceive. After having three sons, who they love dearly, both of them would absolutely love a little girl to dote on.'
