This popular five-member boy band included teen hotties AJ McLean, Howie Dorough, Brian Littrell, Nick Carter, and Kevin Richardson. They shot to fame in the late ’90s with their catchy songs (“I Want It That Way,” anyone?) and drool-worthy music videos. With over 130 million records sold worldwide, they are the best-selling boy band of all time. After taking a three-year hiatus, they re-banded in 2005 to release three more albums (to the utter delight of girls everywhere).
