The Spice Girls - WERE at each other’s throats during rehearsals

The Spice Girls: Geri Halliwell, Emma Bunton, Victoria Beckham, Mel C & Mel B were at each other's throats during the band's rehearsals for their reunion tour, it has been revealed.

And, according to reports, the unbearable tensions have driven Ginger Spice to plaster motivational Post-it notes on her head and around her dressing room to keep herself in a positive attitude.

Britain's News Of The World newspaper reports that the girls' fights included:

Mel B shouting at Geri for mucking up the dance routine for Stop. She apparently screamed: "You’ve got to keep it together, if you spent more attention on your routines then it would be right."

Victoria Beckham then had a pop at Mel B for dancing out of sync to Spice Up Your life: "Next time we all have to stand in line and get it right," she quipped.

The other girls reportedly criticized Victoria for spending too much socializing with her A-List pals Tom Cruise and Kate Holmes when they turned up to watch the rehearsals with their young daughter Suri.

And, according to an insider, the current tensions stem from the fact there are so many expectations on the famous five.

The girls' various dressing room demands have also been revealed.

Posh Spice, 33, reportedly insisted that she had seven clothes rails, a web spy system to check in on her kids, two designer sofas, computer games for her kids, an Apple computer, a poster of Audrey Hepburn, a massage chair, and Acai-Plus health juice on tap.

And Geri's demands included a full supply of Post-it-notes for her motivational tips, a huge picture of her and pal George Michael and five clothes rails.

Melanie Brown’s room is full of safari paraphernalia - while Melanie Chisholm’s has to be floral and homely.

And Emma’s simply has a cot for baby Beau and one clothes rail, reports the News Of The World.
