AJ McLean, whose symptoms are said to include heavy drinking, is receiving treatment for his condition...

BACKSTREET BOYS have postponed a series of live dates in North America to allow band member AJ McLEAN to receive treatment for depression.

The band are currently on their ‘Black & Blue’ world tour. However, the group have postponed the next month of the tour, which included last night’s show at the Boston Fleet Centre (July 9), so McLean can undergo the 30-day treatment. His symptoms are said to include heavy drinking.

Speaking to MTV about the show postponements, group member Brian Littrell said: “(McLean) came to us yesterday and said, ‘Guys, I need help. I looked at him in the eyes and said, ‘I’m proud of you.’ That’s the first time he said it to any of us: ‘Guys, I have a problem, and I wanna better myself and better the group and better our situation.’ “

Fellow member Nick Carter added: “We approached AJ in Orlando when we felt it was going to influence the tour. I was worried about him vocally, I was worried about him physically. He has a lot of duties when it comes to performing. We wanted the fans to get the best show possible.”

It is expected that the tour will resume at the Vancouver GM Palace on August 7. All the dates that have been pulled will be rescheduled, and tickets are valid for the new dates.
