With so many celebs and non-celebs in rehab these days, let’s take a moment to see how our all-stars are faring in rehab and post-rehab.

Colin Farrell

In rehab for: Addiction to pain medication and exhaustion

What the rehab ordeal has taught him: The Miami Vice and S.W.A.T. actor once said “[Rehab] was horrible in one way, because I went away because I was pretty sick. But in another way it was great, because it was a very safe environment with a bunch of people who were looking to sort out things in their life. But I don’t want to go back.”
The Irish hunk known for his hard partying says he did his time in rehab [December 2005-January 2006] for his son James, 3, because after fifteen years of craziness, just wanted to be a better dad. “I wanted to be clear, be around him, and remember being with him.”

Update: So far, so good!

Lindsay Lohan

In rehab for: Alcohol addiction

What the rehab ordeal has taught her: Nothing. She’s still partying, boozing and doing drugs as hard as ever.

Update: Same old party whore

Britney Spears

In rehab for: Heavy-duty partying, Depression

What the rehab ordeal has taught her: That the next time she needs help, she needn’t flash her privates or go bald.

Update: She’s still in rehab...That’s always a good sign.

Charlie Sheen

In rehab for: Addiction to drugs

What the rehab ordeal has taught him: ‘Rehab is a dumping ground. It’s a big dumping ground. I was never shut down by the drugs; that was my problem. Cocaine was an aphrodisiac. I think that was a bit of a curse,” says Charlie.

Update: Seems to have got his act together, though there are still signs of the ‘old Charlie’ - he still chain smokes cigarettes.

Nicole Ritchie

In rehab for: Drug and alcohol addiction

What the rehab ordeal has taught her: Nicole confessed to Oprah that her parents divorce led to her addition to drugs and alcohol. “I was definitely trying to mask hurt, abandonment. I had no idea I was feeling this way,” she said.

Update: Not too good. Nicole was arrested on a DUI on December 11 and admitting to cops she had used Vicodin and marijuana. According to In Touch Weekly, Nicole’s current drug of choice is Adderall - a powerful appetite suppressant. Shame on you.

Ben Affleck

In rehab for: Alcohol addiction
What the rehab ordeal has taught him: “I’ve never been very judicious about my own behavior or choices until they had an impact on people other than me,” says Affleck, 34, who was driven to Promises rehab by his pal Charlie Sheen in August 2001.

Update: Ever since he got hitched to Jennifer Garner, no glitches at all. Shows you the importance of the right woman in a guy’s life.

Kate Moss

In rehab for: Cocaine addiction

What the rehab ordeal has taught her: Nada.

Update: With a career in the modeling business, where a size-0 is considered overweight, and a drug-addicted boyfriend like British rocker Pete Doherty, I’d say things don’t look good. Kate has been photographed at Pete’s concerts looking totally zonked out.
