Before the boy band -- composed of Kevin Richardson, Nick Carter, Howie Dorough, A.J. McLean and Brian Littrell -- embarks on their DNA World Tour they're reminiscing on almost 26 years of being together at the GRAMMY Museum's Backstreet Boys: The Experience in Los Angeles.
The one-of-a-kind ultimate fan exhibition features the boy band’s mementos, including childhood photos, wardrobe, awards, music video memorabilia and so much more. One thing that will definitely make devoted BSB fans nostalgic are the original "Quit Playing Games (With My Heart)" shirts, which are now dry and in mint condition.
"I'm surprised they stayed in such good condition, is the original shirts we wore from the 'Quit Playing Games video,'" A.J. told ET's Sophie Schillaci at the GRAMMY Museum exhibit on Monday. "Mind you they are dry now, they were soaking wet in the video."
"We had to dig into some of our old warehouses and storage units to find some of these things that we didn't know existed anymore," added Nick. "I mean we went all the way back to our Millennium tour, found the blue outfits that we wore...Just things that people hadn't seen before, or hadn’t seen in a long time. We put together a great collection of things that I think people will be able to remember and recall, and celebrate with us."
Brian's high school diploma, school trophies, fan mail and even A.J.'s baby outfit he wore when he was taken home from the hospital are featured.
"Which in 41 years, I had never seen that," A.J. said. "So thanks mom, appreciate that. Now I'm seeing it behind glass."
The five singers have already had an incredible year, and it's only going to get better. Opening up for their world tour, kicking off May 11, is Brian's 16-year-old son, Baylee, who recently launched his solo country career.
"He didn't have to audition. He's got a little connection," Brian joked about his son joining them on the road, with Kevin adding, "We know that he's got the goods. So he don't have to audition for his uncles."
The night also included a Q&A with KIIS-FM’s JoJo Wright leading the conversation and taking a trip down memory road. The artists shared their first memories of joining the band (Kevin and Brian were the last to join), talked about their epic Black & Blue jet where they traveled the entire globe in 100 hours to promote the album (AJ got to fly the plane), touched on their tumultuous relationship with their ex-manager and BSB founder, the late Lou Pearlman, shared their biggest onstage mishaps (Kevin has had the most technical difficulties), and how they met their wives.
During the hour-plus interview, they also revealed that they would be releasing their first Christmas album. "We're actually going to be working on a Christmas album this year," Nick shared.
"We've done a song or two, but we have never done a Christmas album," added Kevin. "We're going to be doing a full-length Christmas album, some classics and some originals. We are working on that while on the DNA World Tour."
The GRAMMY Museum's Backstreet Boys: The Experience opens on April 10 and runs until Sept. 2, 2019.
