14. David Duchovny
Somebody had to see this one coming. The guy was the host of the softcore Red Shoe Diaries back in the ’90s on Cinemax and played the lead character in Showtime’s Californication. He’s playing a sex addict in both of these roles! Despite being married to Tea Leoni for much of this time period, rumors of him being a sex addict followed him, forcing him to have to tell Playgirl magazine in 1997, “I’m not a sex addict. I have never been to those meetings.” In 2008, shortly after one of his many break-ups with Leoni, the X-Files actor checked himself into in-patient rehab for sex addiction. The couple tried to get back together multiple times, but finally divorced in 2014.
