So Harry Styles may have five nipples, but when it comes to abs of steel, those One Direction Boys don't hold a candle to New Kids On the Block.
Donnie Wahlberg, 45, posted a photo to Instagram of himself with Danny Wood, 46, and Joey McIntyre, 42, which shows off their seriously impressive physiques (age is no excuse for these guys!)
The photo was captioned:
"Not bad for a few old men! Hard work pays! #TheMainEvent"
Jordan Knight, 45, isn't in the above photo, but rest assured, he's just as chiselled!
Jonathan Knight is not quite as forthcoming with the shirtless shots, but he's still looking damn good for 46. All in all, the NKOTB fellas look amazing - hard work really does pay off! To think they rose to fame before the One Direction boys were even born!
The One Direction boys do have an adorable youth working in their favour, however they're not even close to as ripped as their boy band predecessors are. Louis Tomlinson is 23, while Harry, Niall Horan and Liam Payne are all 21 and Zayn Malik, 22 (no longer a member.)
Regardless, you can find a plethora of shirtless snaps and gym selfies on their Instagrams.
