Robin Williams has entered rehab for the second time, but not because he has relapsed.
"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," a rep for the actor said in a statement released on Tuesday.
Williams, 62, is reportedly spending a few weeks at a Minnesota renewal center called Hazelden Addiction Treatment Center. On June 29, the Crazy Ones star was spotted at a nearby Dairy Queen in Lindstrom, Minnesota, where he happily posed for a photo with one of the workers.
Williams has been open about his longtime battle with drugs and alcohol. In 2006, he sought treatment for alcoholism after 20 years of sobriety. His rep said at the time that the comedian had "decided to take proactive measures to deal with this for his own well-being and the well-being of his family."
"It's [addiction] — not caused by anything, it's just there," Williams told Diane Sawyer in October 2006. "It waits. It lays in wait for the time when you think, 'It's fine now, I'm OK.' Then, the next thing you know, it's not OK. Then you realize, 'Where am I? I didn't realize I was in Cleveland.'" Williams revealed he had spent two months "club medicated" in Oregon's Hazelden Springbrook treatment center.
Williams first became addicted to alcohol and cocaine while starring in the sitcom Mork and Mindy from 1978-82.
"Cocaine for me was a place to hide," he told People in 1988. "Most people get hyper on coke. It slowed me down. Sometimes it made me paranoid and impotent, but mostly it just made me withdrawn. And I was so crazy back then — working all day, partying most of the night — I needed an excuse not to talk. I needed quiet times and I used coke to get them."
Williams married his third wife, graphic designer Susan Schneider, in October 2011. He has three children — son Zachary, 31, from his first marriage and daughter Zelda, 24, and son Cody, 22, from his second.
