A.J. McLean has checked himself into rehab.

The Backstreet Boys singer - who has previously been treated for depression, anxiety and excessive consumption of alcohol - voluntarily checked himself into a treatment Clinic on Monday (10.01.11) after realising he needed help, but insisted it would not affect the group.

In a statement he said: "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 and 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."

Its gonna be a great year! I love u all and wish me luck! I start my sober Journey tomm! Ttfn! (sic)"

He added in a post on Monday: "Hey all wish me luck! 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!(sic)"
