David Duchovny In Rehab For WHAT?

Believe it or not David has has been admitted to rehab suffering from ‘sex addiction’. Duchovny  told People magazine: ‘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’.  I wonder why they decided to have a press conference and announce it rather than just go into rehab quietly.  Wonder if some tabloid has some dirt on him that they are about to release?
