Backstreet’s back, alright… and selling out one of the world’s currently most sought after venues.

In case you’ve missed it, Nick has rejoined the Boys this Summer to revive their Millennium era, the band’s biggest era to date, at Sphere in Las Vegas. Since the beginning of July, they have been performing to sold out crowds every weekend with not only their biggest fans from all over, but celebrities ranging from Chrissy Teigen to Post Malone to Usher to Macauley Culkin and Brenda Song in attendance.

Nick’s favorite audience members though? His three little ones, of course, who he has shared photos and videos of throughout the past few weekends on his Instagram, dancing along to the show and joining Dad in the photo booth!

“As I was about to come up, I started breaking down and crying because it was so emotional and surreal. We’ve been together so long and had so many ups and downs, so the fact we can still perform on any stage is amazing,” Nick recently told The Hollywood Reporter about performing this residency, with USA Today calling the concert “stunning”.

You can catch the Boys for a few more weekends at Sphere through August 23rd – don’t miss it!
