Backstreet Boys are in negotiations with the Spice Girls for a joint world tour.
Brian Littrell of the US boyband said discussions are underway for the global dates, reported MTV online.
"We are actually in early talks about maybe doing a world tour together with the Spice Girls," Littrell said.
The Spice Girls last performed at the closing ceremony of the 2012 London Olympics. That appearance came five years after their original reunion tour The Return Of The Spice Girls.
