The End of the Spice Girls?

The Spice Girls may likely never tour again. Geri Halliwell tells Billboard.com that she doesn't expect a sequel to the Return of the Spice Girls World Tour, which wraps up Feb. 26 in Toronto.

Halliwell, who was influential in reuniting the girls for the tour, says, "It probably won't happen ever again. I'm still absolutely blown away that we did more than one show. So right now, I'm thinking this is it. This is the last time you will ever get to see this Girl Power, the five Spices, on the stage as one."

Although the girls are disbanding amidst rumors of internal fighting, Halliwell has nothing but good things to say about the tour, calling it "amazing ... an experience of a lifetime. I couldn't have asked for it to be better, actually."

Halliwell added, "Actually, it's gone on longer than planned because we thought we were only going to go to the end of January. After February, everybody had commitments -- kids had to go back to school and that. So we had to leave places out that we would have loved to have gone to."

Post Spice Girls Tour, Halliwell plans to debut the first in a new children's book series featuring a character named Ugenia Lavender, who Halliwell describes as "a rebirth of girl power."
