Back in February Victoria Beckham crushed the hopes of fans around the world after revealing she will not be going on tour with her former bandmates.
The designer, who is celebrating the 10-year-anniversary of her first collection, opened up about her reunion with the girls: "I’m not going on tour. The girls aren’t going on tour," the Wannabe singer told a UK publication.
Posh Spice released a touching message to her former bandmates following today's tour news. "Being in the Spice Girls was a hugely important part of my life and I wish my girls so much love and fun as they go back on tour, I know they will put on an amazing show and the fantastic fans past and present are going to have a wonderful time!"
The foursome will kick off the girl power tour on June 1st 2019 in Manchester, England.
