The 90s girl band - also made up of Mel B, Geri Halliwell, Emma Bunton and Mel C - were reportedly set to perform a string of concerts in Australia next year and sources had claimed all five members would be involved.
However, Victoria - who has carved out a hugely successful career as a fashion designer - doesn't want to take part and will not be joining them.
The mother-of-four's spokesperson told The Sun newspaper: ''Victoria has no plans to tour with the Spice Girls in 2014. Her future focus concerns her family and fashion business.''
However, the four remaining members are still keen to do it and look set to go ahead without Victoria.
The girls last performed together as a five-piece at the London 2012 closing ceremony and Mel B said they were keen to go on tour again.
She said: ''We're always talking about getting together. We always have cups of tea and dinners together. We're all friends at the end of the day.''
Before the Olympics the group last performed together in 2008 as part of their comeback tour.
