WATCH: Backstreet Boys Show Us What They're Made Of In New Music Video

The Backstreet Boys are making good on their comeback effort. Not only did they release a new album and embark on a world tour, they also released a video in support of marriage equality. Now, they are rewarding us with all their hard work by taking it off in the new music video for "Show 'Em (What You're Made Of)." Brian and A.J. man up and strip down in the intimate new video, which also serves up some great Nick Carter biceps.

Considering Brian is almost 40, he looks damn fine.

And A.J. is turning into a nice bear of a man.

The full video is hosted on the group's Facebook page but you can watch the teaser below:
