Backstreet Boys star A.J. McLean has checked himself into rehab again since his substance abuse issues seems to be seriously interfering with the band’s plans to tour with the New Kids On The Block.

New Kids On The Block, Backstreet Boys Announce NKOTBSB Tour Dates

A.J. released a statement saying, “For personal reasons, I’ve checked myself into a rehab clinic. With 2011 being a busy year for Backstreet, I want to be healthy and perform & sing for people at my very best and happiest. None of this will affect our current tour plans and I look forward to seeing everyone really soon! Thank you for all of your support and respecting my family and friends privacy during this time.”

The 33 year-old, who was allegedly totally wasted on a Backstreet Boys cruise last month, has battled alcohol and cocaine abuse for years. A.J. checked into rehab in 2001 and 2002, but the struggle is far from over.

On January 9, AJ tweeted, “I love u all and wish me luck! I start my sober journey tomm!” And the next day, he sent out a very cryptic message, saying, “See u on the other side!” We hope A.J. finally finds peace and a solution for his problem. The BSB/NKOTB Tour will not be affected by the singer’s rehabilitation plans.
