Listen to Backstreet Boys on iHeartRadio

The Backstreet Boys are taking a stand for marriage equality.  The former boy band debuted the music video for their new single "In A World Like This" on  "Good Morning America" Thursday - making a statement about where they stand on the issue. 

The video takes a look at moments in American history like the man on the moon and the September 11th terrorist attacks.  It ends with a lesbian couple  watching gay marriage being legalized on television. 

A.J. McLean's tells the ABC morning show the video "tells a story of how love conquers all" and that the group wanted to take the opportunity to "show our support for the LGBT community."  

The Backstreet Boys' new album is out on July 30th and their 20th anniversary tour kicks off on August 2nd in Chicago.
