She famously snacks on edamame beans, and frozen grapes and endures a diet of steamed fish and raw vegeatables to keep a svelte size 6 frame.
But Victoria Beckham has insisted that she is just like the average woman, especially when it comes to her catwalk creations.
In a stunning photoshoot for the British edition of high fashion glossy Harper's Bazaar, the married mother of four said she represents the general public, especially when it comes to testing out her own designs.
The revealing interview was accompanied by glamorous photos of the star in swimwear, which was very reminiscent of old Hollywood stars and pin-ups Elizabeth Taylor and Marilyn Monroe.
Victoria explained that since she became a designer she prefers to wear her own clothes to feel more at one with the customer. But last year she was disappointed she couldn't do that when she was pregnant with her long-for daughter Harper.
She told Harper's: 'We always joke that we have this fabulously gorgeous 17-year-old model who is six-foot-whatever and then I say "OK, I’m going to put it on. I stand for the general public here".
'It’s how I work. I found it really difficult when I was pregnant and I couldn’t do that. It’s part of the process - I’ll stand here in my knickers and start draping fabric over myself. It was very hard when I didn’t have my body.'
