The Spice Girls’ London comeback concert sold out in just 38 seconds, the show’s promoters said yesterday.

More than one million people in the UK registered for the December 15 show.

Those who successfully registered for the O Arena concert were sent an email or text message last night saying that they could collect their tickets this morning.

Three new London dates, on December 16 and 18 and January 2, have been added to the tour.

Tickets for the December 15 gig are already appearing on eBay, for as much as £750.

Scary, Sporty, Ginger, Posh, and Baby Spice launch their world tour in Vancouver, Canada on December 2. They will also perform in other cities including Los Angeles, Las Vegas, New York, San Jose, Shanghai, Madrid, Beijing and Cape Town.

This will be the first time that the Spice Girls have been on stage together since Geri Halliwell quit in May 1998.

The bookmakers Ladbrokes are now offering odds of 1-4 that the Spice Girls will have a Number One single by the end of the year, and 3-1 that the group records this year’s Christmas number one.

Nick Weinberg, a Ladbrokes spokesman, said: “The 38-second sell-out proves that the girls are still very much in demand.”

Geri Halliwell, Victoria Beckham, Emma Bunton, Melanie Brown and Melanie Chisholm sold more than 55 million records around the world.

The December 15 concert is the fastest-selling show at The O2 . A computer selected 20,000 of the million applications at random and emailed the fans.

In the US, Spice Girls tickets are selling for as much as $2,000 (£1,000) on eBay.
