The Spice Girls have added some more dates to their forthcoming world tour.

Extra gigs have been arranged for Shanghai, Vancouver and San Jose and they will play another concert in Anchorage or Zagreb, with the two cities competing in an online poll.

Ginger Spice Geri Halliwell said: "I always felt in my heart the reunion had to happen and it was the right thing to do.

"Having said that, we haven't been together for many years, and so when we put up the availability to register to come and buy tickets, you don't know, maybe two people want to come , maybe twenty, maybe lots. And it turns out that 3 million people registered. That's 18 million people who want to come and see the Spice Girls.

"We are like the Waltons. We are taking all seven children, one husband, a few boy-friends, five grown-up women and all their stuff.

"We really pride ourselves that we have always loved our families and we've treated each other like family."
