The Spice Girls wannabe stars again. Following a calculated publicity buildup, the original Girl Power group of the 1990s announced Thursday that they have agreed to reunite for 11 concerts around the world in December 2007 and January 2008.

“Imagine you got divorced and you’ve got back together with your ex-husband,” Halliwell said, explaining how she felt about the reunion.

“She just appreciates the fact we’ve let her back in,” joked Victoria “Posh Spice” Beckham.

The group said the shows would be in Los Angeles on Dec. 7; Las Vegas on Dec. 8; New York on Dec. 11; London on Dec. 15; Cologne, Germany, on Dec. 20; Madrid, Spain, on Dec. 23; Beijing on Jan. 10; Hong Kong on Jan. 12; Sydney, Australia, on Jan. 17; Cape Town, South Africa, on Jan. 20; and Buenos Aires, Argentina on Jan. 24.

Halliwell and Beckham joined with Melanie “Sporty Spice” Chisholm, Emma “Baby Spice” Bunton and Melanie “Scary Spice” Brown to pose for photos and announce tour plans.

In conjunction with the tour, EMI said it plans to release the first Spice Girls greatest hits album in November. The group also plans to make their first official documentary for TV broadcast.
