WATCH: NKOTBSB Get Ready to Kick Off New Tour


Two of the most popular boy bands of all time, New Kids on the Block and the Backstreet Boys, have combined to put on one legendary tour for their faithful fans and we were there as they got ready the day before their first tour date.

The two bands shared one stage for the first time at the 2010 American Music Awards in November and AJ McLean called the crowd's reaction to that performance "the spark" that ignited the tour's launch.

The bands have gotten well acquainted as Donnie Wahlberg revealed, saying, "We know who's got the bad hygiene habits, whose gas is the worst … We kind of know a lot about each other now."

As if the news of NKOTB and BSB uniting wasn't enough, now "Glee" star Matthew Morrison will reportedly join the tour on July 6 in Anaheim, California and continue with the band through August 7 in London, Canada, according to the Los Angeles Times.

The new NKOTBSB tour kicks off Wednesday night at the Allstate Arena in Rosemont, Illinois. NKOTBSB's first single "Don't Turn Out the Lights" is available on iTunes.
