THE New Kids on the Block are regressing on their world tour. The two single “kids,” Donnie Wahlberg and Danny Wood, have had a stripper pole installed in their bus while the band is on tour. An insider said, “They’re living it up big time.” A rep for the duo said, “Just for laughs, they do have a Carmen Electra stripper pole that was given to them as a tour gift from their publicists. It’s all in good fun. It came with an instructional video so they can follow all safety procedures.”
