Donnie Wahlberg got back to his teen pop-star roots and has been touring with New Kids on the Block all summer as part of The Package Tour.
Just before one of his shows in July, the "Blue Bloods" star decided to give his fans a little something extra. "Pre show shower time!" he tweeted with this nearly nude photo.
This Wahlberg brother, who is currently linked to funny gal Jenny McCarthy, is certainly not shy, as he's already added it to his Twitter page's wallpaper. For more Donnie Wahlberg ab action, please see this twitpic, this twitpic and this twitpic.
