After half-assedly making good on their promise of a comeback tour and collecting massive paychecks that would even make dear Dick Fuld seethe with envy, the Spice Girls were always wont to dabble in more meaningful exploits posthumously. So what in Spice World are those loony broads up to now? Well, one plays high-stakes, high-fashion games of peek-a-boo -- but you probably knew that. Another mistakes our desire to see her perform a high-kick with a desire to see her continue singing, so she's exchanged her trainers for a pair of orthopedic sneakers and refashioned herself as a less-successful Melissa Etheridge. The third, meanwhile, squanders her golden years yammering about the merits of carbs. And the fourth. Sigh.
