British pop star Kate Nash has hit out at the upcoming Spice Girls reunion tour, accusing the girl group of reuniting just for the money. The FOUNDATIONS singer believes the newly-reformed Spice Girls' 14-date world tour will be "embarrassing". She says, "I'm not excited about it at all. Why do they have to do it? Do they need to do it? It's obviously just about money. I think it will be embarrassing. "They're all older now, so, to kind of still want to be the Spice Girls is just, I don't know... Just grow up."
