The Spice Girls are cutting back their reunion tour "due to family and personal commitments." Summer concerts in China, South Africa, Australia and Argentina have been canceled; the trek will now end Feb. 26 in Toronto.

"Sadly the tour needs to come to an end by the end of February due to family and personal commitments for Emma, Geri, Mel B, Melanie C and Victoria," reads a statement from the group's publicist.

"It was announced in June that, as well as the Europe and the U.S., the girls planned to visit Australia, China, South Africa and Argentina. Due to the phenomenal demand for tickets in the U.K and the U.S. along with the touring logistics for such a massive production it was not possible to fit everything in."

"We want to thank everyone who came to see us," the group wrote on its Web site. "It was all so mad the first time round, so we've really been able to appreciate it properly this time."
