Donnie Wahlberg tweets shirtless New Kids on the Block pic

They're still hanging tough -- only this time with mustaches. All five members of New Kids on the Block posed for a shirtless 'stache pic in what looks like a locker room on Wednesday (July 18), and luckily for fans of the boy band, Donnie Wahlberg tweeted it out.

"After 3 months cultivating, countless insults, thousands of requests to shave the ‪#stache," Wahlberg posts along with the pic, which shows himself, Joey McIntyre, Jordan Knight, Jonathan Knight and Danny Wood all donning facial hair and little else.‬

Mustaches notwithstanding, the guys are looking pretty good, don't you think?
