Backstreet Boy Brian Littrell claims there's one big difference between A.J. McLean's current stint in rehab and his last one -- no one FORCED him to get help this time.
Brian went on Bob 93.3 in North Carolina this morning, telling the host, "I'm proud that he would go into this situation willingly ... Last time it was a lot worse. He really went into rehab unwillingly the last time."
According to Brian, A.J. decided to commit to rehab over a month ago ... while the band was on the road.
A.J. McLean's issues with substance abuse have been the source of MAJOR problems in the past several months ... and it got so bad, that staffers on the Backstreet Boys' tour threatened to walk if he didn't get help.
TMZ has learned A.J. -- who's struggled with abuse for years -- was so hammered and rowdy on a BB fan cruise last month, that several passengers lodged complaints ... with some even demanding a refund.
One cruise staffer tells us A.J. and his crew acted like "drunken fools" for the entire five-day trip.
But after the cruise, the abuse continued ... and more people in his life threatened to jump ship.
Sources close to the singer tell us A.J. became so difficult to work with during rehearsals for the upcoming BB tour that multiple people were "ready to quit."
Fortunately, A.J. decided to check himself into rehab a few days ago -- but he insists he'll be ready to go for his upcoming tour.
A.J. McLean from the Backstreet Boys has gone into rehab again ... TMZ has learned.
One source tells TMZ McLean has been "out of control" in the last few months because of substance abuse, and it was interfering with plans for the Backstreet Boys' upcoming tour with New Kids on the Block.
Sources say on a Backstreet Boys cruise last month ... A.J. appeared under the influence much of the time.
McLean has battled addiction for years. He was in rehab in both 2001 and 2002 for alcohol and cocaine abuse.
McLean made a cryptic reference on his Twitter account, writing on January 9, "I love u all and wish me luck! I start my sober journey tomm!"
On January 10, McLean tweeted, "See u on the other side!"
Video shot during a BSB cruise for fans last month shows McLean with what looks like a beer -- amber liquid with foam on top.
UPDATE: 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."

It was all for a session with photographer Tyler Shields -- the guy who shot those semi-naked Lindsay Lohan "Inferno" pics.
