The stars of The Hills have had some up-and-down moments. Now, one of them in particular is coming clean about drug issues in light of the tragic passing of Philip Seymour Hoffman last week.

The Hills hottie Jason Wahler — who dated Lauren Conrad but is now married — has had several stints in rehab to deal with his addictions. This week, he writes about how Philip's death reminds him of the bad choices he made and how difficult it can be to kick the habit. 

"A few years ago, I would host parties at my house in L.A. where there would be 50-100 people raging out of control," Jason admits. "While everyone thought I was enjoying the party as much as they were, little did they know I was secretly going into the master bathroom and snorting as much coke and drinking as much alcohol as I could."

"It can be incredibly hard for people who haven't been afflicted with addiction to understand the thinking and behaviors of an addict," he adds. "I have witnessed just how close-minded some people can be when it comes to addiction, and combined with the passing of Phillip Seymour Hoffman, it only drives me to keep pushing to raise awareness."

We admire Jason for wanting to help others and for being so open about his past.

Are you surprised by what Jason is admitting?
