In one of the worst kept secrets ever, the Spice Girls are gonna show the world what being British is all about at the Closing Ceremony of the London Olympic Games on Sunday.

Pictures have now officially leaked of the theme-heavy quintet rehearsing for the final show. The Girls may be in their street clothes, but don't be surprised if the ol' red, white and blue (the Union Jack, silly) make up a big part of their costumes at the big show.

If you wanna win gold medal... you gotta train for years. The Spice Girls reunion, however, has only been in the works for months, ahead of the bow of their musical theater live show over the holiday season in London.
