The cover is in gold to commemorate the anniversary, and for readers who don't buy into the Beckham school of life there is also an interview with Ewan MacGregor and a day-in-the-life of Cherie Blair.
The MacGregor interview promises to dispel rumours about his marriage and infidelity, while the Blair feature will give readers an exclusive look inside the private quarters of No 10.
The Victoria Beckham supplement comes as her profile is particularly high, with husband David's move to Real Madrid from Manchester United. The A5-format 100-page publication includes what clothes she wears, her favourite restaurants, recipes and holidays, and a photo shoot of her and some celebrity guests.
Marie Claire editor Maire O'Riordan, said: "Working on this issue has been the most fun ever. As well as making readers feel that it's the best of the best, we revved up the celebration mood throughout."
The 15th issue of Marie Claire will be supported by a sales-promotion drive that will see Victoria Beckham lookalikes handing out fliers at WHSmith and other high street retail outlets to draw attention to the magazine.
