Sounds like David Duchovny might be taking his role as womanizer Hank Moody on Californication a little too seriously. The actor has checked himself into rehab for sex addiction. His rep confirmed the news to People with a statement from Duchovny saying, "I have voluntarily entered a facility for the treatment of sex addiction. I ask for respect and privacy for my wife and children as we deal with this situation as a family." As much as we don't want to believe this is really true, most of all it's just sad for David's wife Tea Leoni and their two children. Hopefully he'll be out and back to his family soon with the problem under control before it causes any more pain.
