PHOTO: New Kids On The Block Shirtless And Moustached

Maybe the New Kids on the Block were inspired by news of the Backstreet Boys' reunion, because all five members of one of the original boy bands — (from left to right) Joey McIntyre, Jonathan Knight, Jordan Knight, Donnie Wahlberg and Danny Wood — tweeted a pic of themselves wearing mustaches and not much else, hanging out in a bathroom.

"After three months of cultivating countless insults, thousands of requests to shave the #stache," Wahlberg, who has turned to acting in his post-boy-band days and can be seen in projects like The Sixth Sense, Band of Brothers, Saw II, Righteous Kill, Rizzoli & Isles and, most recently, Blue Bloods with the king of all stachers, Tom Selleck, tweeted with the pic.
