The five ladies will do just that with an 11-date, six-continent world tour, beginning December 7 in Los Angeles, and will include stops in New York, Las Vegas, Beijing, Sydney, Madrid, London and Buenos Aires, among other cities. “That’s a lot of world, a lot of people and a lot of fun,” Geri said.

They plan to sing songs from each of their albums, including the third, 2000′s ‘Forever,’ on which Geri doesn’t appear (she left the group in 1998). But she said that won’t stop her; Mel B plans to let Geri sing some of her lines. The Girls do, however, have a few songs they’re most looking forward to performing. Among them, ‘Wannabe’ (Mel B’s pick), ‘Too Much’ (Victoria’s) — but Mel C couldn’t decide on one. “We’ve got so many great songs,” she said.

When asked what the shows would be like, the whip-smart Geri deadpanned, “There will be five girls, music, lights and topless dancers.”

“Are you going to be doing that?” Mel B shot back.

“We want it to be spectacular,” Mel C said.
