Scary Spice unloaded on Posh telling her: "F*** off, you bitch!" as the two women went to war.
The row happened after – Mel B, Emma Bunton, Geri Horner and Melanie Chisholm — jetted in to London to make promotional material announcing a UK tour.
The performers spent 14 hours at Alva Studios in Hackney, London, filming clips and recording material for promotional purposes.
After months of wrangling the tour will kick off in the UK next May, with extra dates in Europe.
But Beckham, 44, will not be in the line-up following fiery exchanges with Mel, 43, according to sources.
An insider said: "The girls are furious with Victoria for initially agreeing to reunite, then pulling out. At one stage she even threatened to go legal if the girls cashed in on the brand minus her.
"They then took offence to her recreating her Spice Girls looks in a recent Vogue shoot, and basically said she was being a hypocrite.
"By the end of the exchange, Melanie told Victoria: 'F*** off, you b****!'. And that was pretty much the end of the conversation."
It is understood the tour will go on minus Posh with the others netting $10 million each.
Their former manager music guru manager, Simon Fuller, is no longer calling the shots for the band.
It will be run by music company, Modest, whose roster includes Little Mix and Welsh singer Katherine Jenkins.
The tour will feature dazzling costumes, dancers and pyrotechnics, for the fans to enjoy.
The band members have ousted Posh by dissolving their official company Octopus Direct Ltd so they can operate as a foursome.
The firm looked after record sales, merchandise and films and boasted a massive $40 million turnover during the 1990's.
But after the massive bust-up Posh is being cut-out of the deal.
