The truth is out there, even if we don't want to believe it.

In the week's most WTF?-worthy news, David Duchovny has checked himself into rehab to undergo treatment for sex addiction.

"I have voluntarily entered a facility for the treatment of sex addiction," Duchovny said in a statement released yesterday by his attorney. "I ask for respect and privacy for my wife and children as we deal with this situation as a family."

We should have been tipped off by the actor's IMDB resume. Not only does Duchovny currently star as a skirt-chasing womanizer in Showtime's Californication, he once played the sex-obsessed narrator on cable's softcore Red Shoes Diaries, as well as a sex addict in 2005's Trust the Man. In the film, Duchovny's character attends Sex Addicts Anonymous meetings but soon discovers that his proclivities aren't as extreme as his fellow addicts', so he begins to concoct stories involving sex and cold cuts. (Let's hope his real-life appetites are more mundane; we don't need another reason to be freaked out by deli meats this week.)

The X Files star has been married to actress Téa Leoni since May 1997. The couple, who recently relocated from Los Angeles to New York, has two children: daughter Madelaine West, 9, and son Kyd Miller, 6.

This isn't the first time rumours about Duchovny's randiness and roving eye have surfaced. As if we needed more proof that everything anyone ever says will always come back to bite them in the ass, the actor dismissed the allegations in an interview with Playgirl in 1997, announcing: "I'm not a sex addict. I have never been to those meetings. It's hurtful to my family and if I was involved with a woman in a monogamous relationship, it would be hurtful to her...It's not funny and I'll be glad when it goes away."

Don't expect it to go away until you complete your treatment, buddy. Which leads us to wonder, how exactly do sex addicts detox? Are they forced to concentrate on the universe's unsexiest things, like Madonna's veiny arms and Heidi Montag's music videos?
