Golfer Tiger Woods is undergoing treatment at a Mississippi sex rehab center, according to a writer with The New York Times who is himself a recovering sex addict.

Benoit Denizet-Lewis, author of a book titled America Anonymous: Eight Addicts in Search of a Life who blogs The New York Times magazine, reports that a source confirmed to him Tiger Woods is in a sex rehab clinic in Hattiesburg, Miss.

Denizet-Lewis, an admitted recovering addict, says that he was at the same Pine Grove Behavioral Health and Addiction Services a few years ago while writing his book. Treatment consists largely of group-therapy sessions in addition to family and couple's therapy, he told USA Today.
