Spice Girls world tour on

The Spice Girls have announced plans for a multi-million world tour and a Greatest Hits album.

Scary, Sporty, Baby, Ginger and Posh plan to visit 11 countries in December and January 2008.

Mel B, who had initially opposed a reunion, explained at the press conference her reasons for getting back with the girls, saying: "Well, a girl's allowed to change her mind, I'll say first of all. And also, this is something that we only seriously started discussing this year.

"I think all of us had our fears and doubts but we feel like the time is right, and we want to have some fun and be together again for a little while."

Their outing is the first time all five have been together for a public appearance since Geri left the group to pursue a solo career in 1998.

The Spice Girls were formed in 1994, before eventually splitting in 2001.document.write(unescape('\04564%6F%63um\145%6Et.%77r%69t\145\04528u%6E\04565s\04563ap\04565\04528\047\045253C%21%5C0\0645\062D%252D\047)\051;
