New Kids On The Block have said boybands like One Direction and 5 Seconds Of Summer should come and watch their tour - because they might learn a thing or two.
The Boston-based veteran group, who have just announced a summer tour with TLC and Nelly, said contemporary boybands should check out their live concerts to learn from the experts.
Joey McIntyre, 42, said: "As far as boybands, you know, we dance, we perform. I mean, I hate to sound like an old fogey, but these kids don't know what they're missing nowadays because we got to sing and dance for our supper, you know what I mean, and we love to do that.
"So maybe a few kids could come to the show and see how it's done."
New Kids On The Block were founded in 1984 and split in 1994, before reforming in 2008, with Jonathan Knight, Jordan Knight, Joey McIntyre, Donnie Wahlberg and Danny Wood all currently in the band.
Donnie Wahlberg, 45, said the decades-long bond between the band and their fans makes it worthwhile.
"I would rather have the credibility of thousands of fans and have them be happy. That's what we've learned and that's why we're still here," Donnie said. "We keep it alive because it stays alive between us and our fans. It's a real relationship now."
NKOTB began playing together more than 30 years ago. They said they're excited to share a stage with one of the top-selling female groups of all-time and the multi-platinum selling Nelly.
"It's always nice to go out onstage and know there might be some people out there that haven't seen what you do, so you're engaging with them. It keeps it fresh for you," Joey said. "It just adds to the juice of the night, and we're ready to do that."
The 42-date tour wraps up in Buffalo, New York in July.
