Updating an earlier story, the Backstreet Boys have postponed their summer North American tour through Aug. 7 so group member AJ McLean can enter a treatment program for clinical depression, according to the group's spokesperson. The illness has "recently led to anxiety attacks and the excessive consumption of alcohol. A key factor causing this depression is the recent death of McLean's grandmother, with whom he was very close," the statement reads.

"It's been suggested that we not be so forthcoming about this situation, as many artists in the industry have in the past, but we feel compelled as a group to be honest with our fans and not let them down," the group said in a statement. "AJ is our friend and our brother and we whole-heartedly support him during this difficult time. Fortunately, AJ has realized he can't solve his problems by himself."

"Because he is unable to be on tour at this time, we are postponing dates and will make them up as soon as we can," the statement continued. "At the same time we trust that our fans -- who've always stood by us -- will understand this decision is absolutely necessary in order for AJ to be well. We look forward to seeing all of you on the road soon."

Earlier today (July 9), three shows in Boston were postponed after group member Nick Carter reportedly broke his hand over the weekend. No additional information has been released about Carter's injury.

Tickets for the postponed shows will be honored at the rescheduled dates, listed below. Refunds can be obtained at point of purchase.
