New Kids on the Block was one of the biggest acts of the late '80s and early '90s, and its members were bona fide teen heartthrobs.
Flash forward to 2017, and they're still a top touring act... and still in tip-top shape!
Lead singer Jordan Knight, 47, is currently flaunting his physique on tour during a sexy performance of the group's new song "Hard (Not Luvin U)," lifting his tank to reveal rock-hard abs, and later dropping to the stage for some hip-thrusting.
It's hard to believe it's been 33 years since the band first got together, but they've clearly still got it together!
Watch the performance here.
NKOTB is wrapping up a successful tour, and will next be greeting fans on a Carnival Triumph cruise to Cozumel, Mexico.
