Update: We hate to be the bearers of bad news, but it looks like this epic world tour was just to good to be true. According to MTV News, a rep for BSB stated that the BSB/Spice Girls world tour is a no-go. (We'll just be over here, crying into our '90s-era posters.)
It's like all of our '90s nostalgia was gearing up for this moment: the Backstreet Boys and the Spice Girls may be doing a reunion tour together! Brian Littrell of BSB was the one to allegedly reveal the Internet-breaking news himself.
