Backstreet Boys -- which consists of A.J. McLean, Howie Dorough, Nick Carter, Kevin Richardson and Brian Littrell -- is the best-selling boy band in history, with in excess of 130 million albums sold worldwide. They are also the only group since Sade to release seven consecutive albums in the Top 10 of the Billboard Top 200. Along the way, they have earned multiple Grammy nominations, launched record-breaking tours, scored hit songs like "Quit Playing Games (with My Heart)" and "I Want It That Way"; and, earlier this year, received a star on the Hollywood Walk of Fame. In July, Backstreet Boys released their eighth studio album, In a World Like This in celebration of their 20th Anniversary. BSB are currently in the midst of a massive world-tour that will see the boys perform throughout 2014.
