Former Spice Girl Victoria Beckham has been keeping herself fit by hiking in the Hollywood Hills

Victoria Beckham is a secret hiking enthusiast sources have told Reveal magazine. "It was a surprise to say the least that Posh is into hiking. She's rarely seen out of tight-fitting designer dresses - let alone hiking gear," a source says. "It would be interesting to see whether she wears hiking boots. But then, she once wore high heels for playing baseball - so perhaps she goes on long walks in the California wilderness in her Louboutin heels! Good for them if they are getting out in the fresh air." For more on Posh's LA life check out this week's Reveal magazine out tomorrow.
