It's hard to believe it's been two decades since The Backstreet Boys delivered the most meaningful lyrics to screaming girls everywhere: "You are, my fire."

Since they got together, BSB has sold more than 130 million albums worldwide and the group was just nominated for a Grammy.

"They love it, but we are not the biggest fans of it," said AJ McLean.

Brian Littrell said it can be challenging heading out on tour.

"Like Kevin said, we're all family men -- we're all married, we all have kids," he said. "It just takes a lot of preparation and planning to get on a tour...we don't want to miss soccer practice."
