Just last month, eldest Hanson brother Isaac and his wife Nikki had their second child, a son named James Monroe. That brought the total number Hanson babies to six, but not for long. Middle Hanson Taylor, 25, and his wife Natalie, 24, have announced that they are expecting their fourth child this winter. "Each of our kids has made life richer and more exciting," say Taylor and Natalie. "We can't wait for this guy to join the party."

The Hanson brothers aren't just hanging around making babies with their lovely wives, they are also gearing up for their Walk Around the World Tour, which begins next month. The guys aren't actually walking around the world, but they want to encourage their fans to do some walking of their own. With the goal of reaching a total of 24,902 miles (the equivalent of once around the globe), the Walk Around the World campaign is working to fight AIDS and poverty in Africa one mile at a time.

Who ever could have imagined that those cute boys who sang MMMbop would turn out to be such great family men and philanthropists?
