The Wannabe hitmakers were due to appear on BBC reality show Strictly Come Dancing on Saturday (15Dec07) ahead of their performance at London's O2 Arena the same night - but they have cancelled their performance after Baby Spice fell onstage in Las Vegas on Tuesday (11Dec07) and twisted her ankle.. It's unknown if Bunton will recover in time to perform on Saturday at the first of a string of British performances, the band's homecoming, seven years after they split.. The five Spices arrived in London late on Thursday (13Dec07) and Bunton was pushed away from Heathrow Airport in a wheelchair.. A source says, It's too soon to say if Emma will be fit enough to join the other four girls on Saturday.. She will see a doctor tomorrow, who will assess the damage..
