Once again, reality follows fiction.  David Duchovny, who plays a sex addict on Showtime’s "Californication," has entered a rehab clinic for sex addiction. 

The lawyer for the 48-year-old actor released a statement saying that Duchovny entered rehab voluntarily.  He also issued the standard plea for some privacy, saying "I ask for respect and privacy for my wife and children as we deal with this situation as a family."

Showtime must be licking its chops at all this publicity.  What better to promote a show about sex addiction than to have its star become a sex addict?  "All of us at Showtime wish David and his family the best during this very private time," Showtime said in a statement. 

The second season of "Californication" begins September 28.  If you haven’t seen Californication yet, you should definitely check it out.  It has terrific writing and acting, well-developed characters, a sexy story line, and lots of naked women. 

Duchovny is famous for his role as Fox Mulder on "The X-Files" TV series and in two films.  He married hottie actress Tea Leoni in 1997, and the couple has two children.
