Robin Williams has checked into rehab again.
The 62-year-old actor is seeking treatment at Hazelden Addiction Treatment Center in Minnesota to help him maintain his long-term sobriety.
His representative told TMZ.com: "After working back-to-back projects, Robin is simply taking the opportunity to fine-tune and focus on his continued commitment, of which he remains extremely proud."
It is believed Williams will be spending the next several weeks at the facility seeking professional help.
In 2006, the comedian checked himself into a substance abuse rehabilitation centre in Oregon after admitting he was an alcoholic following two decades without booze.
