On his birthday last Sunday the singer, 33, tweeted “It’s gonna be a great year! I love u all and wish me luck! I start my sober journey tomm!” And the following day he wrote, “This is gonna be an amazing year for me and all around me! I love u all and appreciate all the love and support. See u on the other side!”

Read McLean’s statement after the jump.

“For personal reasons, I’ve checked myself into a rehab clinic,” McLean said this afternoon in a statement from his publicist. “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 is not McLean’s first stint at rehab, but he seems bent on making it his last. Are you looking forward to seeing him, his Backstreet Boys, and New Kids on the Block on tour this summer?
