When Backstreet Boys start their residency at Sphere Las Vegas this summer, tears will flow — but it won’t be from fans overwhelmed by nostalgia.

“I can guarantee you, Kevin [Richardson] will cry multiple times a night. I know he will,” his bandmate AJ McLean tells People. “He’s the most emo, especially the song ‘Back to Your Heart,’ which he wrote. [I] guarantee you, he bawls his eyes out.”

He won’t be the only one crying. I’m sure there are a few members of NSYNC who are ready to try the “Bye Bye Bye” dance again.
