The Spice Girls seem to have done a pretty good job of keeping tight-lipped on their tour. There’s been mostly positive press and decent reviews, though ticket sales haven't been entirely impressive. There have been lots of stories of how family oriented they all are now. But apparently relations behind the scenes were getting pretty tense, leading both Melanie Brown and Melanie Chisholm to quit. Now the entire worldwide reunion/farewell tour has been canceled after only two months of performing. Both Mels officially blamed family commitments, but according to the Daily Mail, they’re just tired of the tour.
However, despite citing family commitments as their reason for cutting the tour short, sources close to the group say the two Mels did not want to continue.
After they were presented with a new tour schedule the friend said to the Daily Mirror: "Mel B wasn't having any of it. She misses her husband and children and said she couldn't go on. She's also been flooded with US offers after her success on Dancing With Stars.
"Mel C agreed it was time to call it a day. She was the least excited about it. She also feared it might jeopardise her solo career."
Officially, a spokesman for the girls said: "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.

I’m guessing there was some drama behind the scenes, though the girls have been very careful to only release positive information. There’s a lot of talk about their personal and family commitments, how much fun they’ve had, maybe they’ll do it again, etc. What I want to hear is about Mel B shoving a raw steak in Posh’s face or Baby Spice trying to kick Geri Halliwell in the head. All this professional politeness is bor-ring. They’ve still got until the end of February to give us what we want.
