Victoria Beckham and Geri Halliwell have reportedly had a huge bust-up over the Spice Girls' future.
The 90s girl band - also made up of Mel C, Emma Bunton and Mel B - were set to reunite once more for a "final fling" world tour as well as releasing a new album.
However, Victoria - who has carved out a career as a successful fashion designer - doesn't want it to go ahead, leaving Geri furious and the pair are no longer speaking to each other.
A source told the Daily Mirror newspaper: "Geri wants the girls to be back on the road as soon as they can. She's been trying to get in touch with Simon for the past few weeks but isn't getting anywhere.
"She and Victoria are no longer talking."
There were reports the girls - who reunited for a 2007 world tour - would go ahead without Victoria but their manager Simon Fuller isn't keen on the idea and won't get behind their plans.
The source added: "A tour without Victoria is a real risk. She may not do a load of the singing but she brings a lot more than people think to the table.
"On their reunion tour she brought Madonna's choreographer Jamie King on board and organised a lot of the outfits with Dolce and Gabbana.
"Simon regards the project as a real risk without VB and without him to mastermind the whole thing it's a tricky situation and probably won't happen."
The girls last performed together at the London 2012 closing ceremony and at the world premiere of 'Viva Forever!' - a musical based on the group's songs - Victoria didn't arrive with the rest of the girls and chose to spend the night with her husband David and their three sons.
