The Spice Girls have added two more London dates for their worldwide reunion tour, after the only UK show sold out in 38 seconds.

Extra shows will be held at London’s O2 Arena on January 15 and 16 after more than a million UK fans registered for the original December 15 show.

The tour brings Posh, Scary, Ginger, Baby and Sporty together for their first pop foray since 1998, and kicks off in Vancouver on December 2.

They will also travel to the States, the UK, Germany, Spain, China, Hong Kong, Australia, South Africa and Argentina.

The Spice Girls greatest hits album will be released a week later than planned - on November 12 - in a bid to avoid clashing with Westlife’s new album.
