Following reports that Reunion Tour rehearsals will soon start in Los Angeles, British music manager Simon Fuller and the Spice Girls are currently considering a long-term show on the Las Vegas strip-a la Celine Dion.

Sources dish that since the Spice Girls are all Saucy Mommies now, Simon is going to have to come up with some child care options in order for the girls to start singing “Viva Las Vegas.”

“They would do a couple of big dates around the world and then settle into six months or so in Vegas,” a mole says. “They can all walk away with a lot more money without having to travel.”
