Shortly after details are announced for the Backstreet Boys/New Kids On The Block "BSBNKOTB" tour, Backstreet's A.J. McLean checks into a rehab clinic.   Story was first reported by TMZ, who has video of a recent cruise where he appears to be drinking beer.     Here's the release from A.J. himself that came out today:

"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."

This isn't A.J.'s first time - he had problems back in 2001 & 2002 for alcohol and cocaine addiction.   Hopefully things will get back on track soon.   What do you think about the "BSBNKOTB" combo - would you go see the tour?
