Unfortunately, Robbie would not go all the way. He has not said which one he needs to bed to complete the set. "I've only got one left to have had all of the Spice Girls," he exclaimed, but named no names.
Geri Halliwell and Mel C would come as no great surprise, as he had public flings with them. That leaves us with Mel B, Emma Bunton and Victoria Beckham left to choose from.
Robbie is currently single but on the look-out for something more long-term than usual.
