It is rare for a week to go by without news of a celebrity or sports star checking themselves into a rehabilitation centre.
Britney Spears, Lindsay Lohan and Tiger Woods have all had their problems.
Whether it is alcohol, drugs or an uncontrollable compulsion to have sex, the addictions of high-profile people attract headlines and a level of treatment few others can afford.
Such is the fascination with showbiz stars and their issues that VH1's Celebrity Rehab has become a big hit.
The show, which features celebrities as they undergo treatment, has reportedly offered Lohan $1m (£652,000) to appear on its next series.
But most celebrities prefer to deal with their problems in private. Many check in to the Promises Treatment Centre in Malibu which offers residential treatment for the well-heeled.
Nestled in the hills above the affluent seaside town, the centre caters for the rich and famous as well as successful business people.
"We jealously guard the privacy of our clients," says Dr David Sack, the centre's chief operating officer.
"We want to ensure that they have the time and the opportunity to get better from their addictions without intrusions so we work very hard to make sure that we don't have our clients on TV or used in the media in any way."
Very relaxed
The centre's focus on privacy meant BBC News was unable to interview any of its current clients, although we spotted a major TV star in the dining room.
In the past, the secluded setting has proved enticing for the tabloid media.
"We have paparazzi who will walk two miles in on public land so that they can try to get a photograph over the mountains behind our buildings," says Dr Sack.

"But you know most people try to respect other people's treatment."
It is an extremely relaxed setting, akin to a residential home for the elderly. There are no locks on the doors and the clients are free to leave at any time.
The atmosphere is homely with a comfortable living room area and a large family kitchen.
Celebrity clients are treated in exactly the same way as everyone else. They take part in group therapy sessions and help with the chores such as cooking and laundry.
But the underlying problems that result in Hollywood's elite seeking help, may be different.
"We think that success creates new pressures and demands on people that add to their anxiety and make them more susceptible to alcohol and other drugs," says Dr Sack.
