The boy band has officially extended their Larger Than Life Las Vegas residency at Planet Hollywood Resort and Casino until the end of 2018.
ET's Keltie Knight got a VIP tour of the stage with Kevin Richardson, Nick Carter, Brian Littrell, Howie Dorough and A.J. McLean, where they talked about their tricks for the show and if any other performers, including Jennifer Lopez and Britney Spears, have left anything behind in the dressing rooms.
"We have an interesting thing that actually happened," Carter told ET.
"We had a record player in the dressing room and it was working, so either J.Lo's kids or Britney's kids tore it up," Richardson said about their joint dressing room. "It's not working anymore."
Speaking of kids, the guys also gave us an update on how their children are doing. McLean's 10-month old daughter, Lyric, "won't take a bottle" yet and Littrell's 15-year-old son, Baylee, has a girlfriend. Meanwhile, Carter is thinking about having a second child.
"There have been some talks," he said about him and his wife, Lauren Kitt, thinking about having a second baby.
The Backstreet Boys are also working on new music and have been hitting the studio, recording their 10th studio album, and will be releasing a single very soon.
McLean is also hoping to work with the Spice Girls, who recently reunited and are "exploring new opportunities together."
"I’m just saying??? Who wants to see this dream, and long mentioned rumor become a reality. Would you come? I know it’s super late and I should be asleep which I’m finally about to be but after I saw the post earlier today from @emmaleebunton page my eyes lit up my heart got excited and the wheels in my crazy head started spinning so???" McLean Instagramed last week. "As they say 'if you build it they will come.' #makeithappen #supertour #bsbanspicegirls? Now let that thought settle in. Good night all."
