Another day, another celebrity sex addiction.

In a recent promo for season 13 of Keeping up with the Kardashians, Scott Disick is seen yelling “I’m a sex addict,” while a distressed Kourtney tells her baby daddy that “it’s never going to work out.”

Disick isn’t the first celebrity to admit to being a sex addict. Anthony Weiner allegedly went last year after he was caught in another sexting scandal. And David Duchovny entered a treatment center in 2008 for the disorder, comedian Russell Brand did the same back in 2005,  And actor Charlie Sheen has said he might be a sex addict.

While it’s not known how many people are sex addicts — and experts disagree on whether it’s a real disorder — some say that between about 3 and 6% of the population may suffer from the affliction.

One thing we do know: Treatment does not come cheap. A 45-day stay at a high-end in-patient sex addiction center can cost between $45,000 – $50,000, says Alexandra Katehakis, the clinical director of the Center for Healthy Sex. And because sex addiction isn’t a clinically recognized disorder — it is not listed in the DSM, the official book of psychological disorders — insurance likely won’t cover it,says Chicago-based psychologist Nancy Molitor, a professor of psychology at Northwestern. 

The treatment is intense. Tiger Woods is rumored to have gone to Pine Grove Behavioral Health and Addiction Services, in Hattisburg Miss., which is one of the only rehab centers solely devoted to treating sex addicts. It’s program includes everything from eye movement desensitization and reprocessing, a psychotherapy that treats trauma; biofeedback therapy, which helps people learn to control their actions; daily small-group therapy sessions to discuss and analyze problems; and a five-day family workshop.

But A-listers also get A-list amenities during rehab. At California-based Promises, which treats sex addiction, you’ll enjoy a swimming pool, tennis courts, jacuzzi, meditation garden and gourmet food.  At Passages in Malibu, you’ll open the door of your room right into a million-dollar view of the Pacific Ocean and get extras like acupuncture and daily yoga classes. You might even get to ride a horse, as Anthony Weiner allegedly did at his sex rehab.

Katehakis, who has treated a number of celebrities, says sex addiction can be a particular problem for them because they have “so much access.” That, combined with the fact that many of the celebrity sex addicts she sees are young men, who aren’t fully mentally mature yet, and may have a touch of narcissisicm mixed in there — creates a recipe for a full-blown addiction.

Even worse: They may never recover. Sex addiction treatments have little long-term success, says Dr. Fran Walfish, Beverly Hills family and relationship psychotherapist and co-star on Sex Box, WE tv.: “While in treatment, they [sex addicts] do well. But it’s not long-lasting,” she says.
