Better give Emma Bunton, aka Baby Spice, two seats on "Spice One," the Spice Girls' Virgin Atlantic tour jet: one seat for her, and one for her over-size accessories, her new crutches. Emma showed up on crutches to a Spice Girls promo shoot with their jet yesterday after falling onstage and spraining her ankle during the group's Las Vegas performance on Monday. "I had a tumble," she explained, "so I'm hobbling around on crutches." She only has a few days before the supergroup's London tour dates, which begin on December 15, but she expects a "speedy recovery." Take baby steps, Baby Spice.
