The Spice Girls‘ 20th reunion tour hit a bit of a snag when Victoria Beckham (Posh Spice) and Melanie Chisholm (Sporty Spice) both decided not to participate — but sources tell Life & Style that rather than cancel the tour, the rest of the group decided to find two ladies to replace them.

“The girls are going to be making a formal announcement about tryouts for their spots in the next few weeks,” the source says. “Posh and Sporty can be replaced.”

Victoria and Mel C, both 42, “are refusing to participate in an upcoming reunion tour,” a source explains. Emma Bunton, 40, and Geri Halliwell, 43, are on board, as well as Melanie ‘Mel B’ Brown, 41, who pushed for the reunion.
