NKOTB Donnie Wahlberg out of control!

Newly-single New Kid on the Block Donnie Wahlberg, 39, has been eating up attention from ladies now that he has split from his wife of eight years, Kim Fey Wahlberg.

On Nov. 7 during the group’s concert at the Borgata Hotel Casino & Spa in Atlantic City, Donnie pointed out to the crowd how nice of a backside he has for his age (complete with a camera close-up), which, judging by the amount of screams, concertgoers agreed!

 And later that night, Donnie partied with fellow bandmates Joey McIntyre and Jordan Knight at Mixx nightclub, cozying up awfully close to one of the group’s dancers, according to an eyewitness.

Maybe Donnie has a new woman after all?
