In 52 days ... the NKOTBSB are going to rock Van Andel Arena in Grand Rapids in a way that will be remembered by those of us who grew up falling in and out of love with these guys!!

Be honest ... who didn't like NKOTB Donnie and then later switch to drooling over BSB A.J. or Howie? All of the New Kids hit the stage way before the Backstreet Boys so, it's not like we're fickle, right?!

Anywho, the two bands are working on recording a new single for their joint album that is set to be released two days before they come to town on May 26th.

It's called "Don't Turn Out the Lights," and will appear on an as-yet-untitled joint album that will also feature five previously released tunes from each group.
