Victoria Beckham works out and runs four miles a day to stay skinny

Celebrity model and fashion designer Victoria Beckham is flashing across mag stands on the cover of December's Harper's Bazaar and she's the first to tell you she didn't play lazy to get there.

Beckham in the past has said she's "very disciplined" when it comes to keeping herself looking slim for fashion.

In a past interview with Harper's, Beckham told the mag "she's not going to pretend she ate a burger before a big red-carpet event, because she didn't.," Harper's says.

"I run four miles a day," says the 35-year-old mother of three. Known for her fad diets and strict eating limitations, Beckham told the new Harper's Bazaar she works out every single day to stay skinny.

"I didn’t want to rely on retouching," she said. "I wanted to look at those pictures in 20 years’ time and say, “Wow, look – after three kids – I didn’t look bad."
