The Spice Girls, pictured at Roberto Cavalli's fashion show in Milan earlier this month, wowed more than 300,000 fans with their comeback tour

Among the audience for last night's concert was David Beckham and his sons Brooklyn, Romeo and Cruz, as well as Bob Geldof, who was there with his daughter Pixie.

David Campbell, chief executive of the O2 told the Standard: "It's been a lovely, friendly, family atmosphere over the past few weeks, we have really enjoyed having the girls here."

He said the venue still hoped to book Michael Jackson later this year.
