The news of Kelly's rehab visit came on the heels of Jack's stint in rehab a year before. The hard-partying teenager admitted to being addicted to the painkiller OxyContin and voluntarily checked in to Las Encinas Hospital in Pasadena, Calif.
Jack's time in rehab had a profound effect on him.
"I took myself out of the picture for a second and I looked around at every single person in the room, at who they were, how old they were and what they had going on in their lives," Jack said in a July 2003 interview with MTV News.
"A lot of them were near 30, unemployed, living off their parents," he said. "There were heroin addicts, there were the world's biggest couch potatoes. And it was like, 'I don't want to be like that. I don't want my life to be controlled by a drug.'"
Jamie Lee Curtis
Curtis debuted in independent horror films, like "Halloween" and "Prom Night", as the sexy ingenue who always outwitted the bad guys. But the "scream queen" was less successful at evading her off-screen demons.
Curtis, also a recovering alcoholic, began taking painkillers after a cosmetic procedure and became addicted to them.
"I would anesthetize myself on a daily basis," Curtis said in an interview with Reader's Digest. "And I found painkillers were very helpful because they did the job without the messiness of alcohol. When my mother was so ill, there was a lot of pain medicine around. The bottle of liquid codeine that sat on her bathroom cabinet — don't think I didn't see it."
Curtis has since worked to overcome her addictions.
She sits on the board for the National Center for Addiction and Substance Abuse at Columbia University and forgoes many film projects in favor of spending time with her husband, actor Christopher Guest, and their two children.
The Grammy- and Oscar-winning recording artist makes no secret of his history of drug use.
Eminem, born Marshall Mathers, rapped about his drug use in songs such as "Drug Ballad," "These Drugs" and "Under the Influence." His song "I'm Shady" on "The Slim Shady" LP, released in 1999, includes the line: "Well, I do take pills, don't do speed/don't do crack, don't do coke/I do smoke weed/don't do smack/I do do 'shrooms, do drink beer/I just wanna make a few things clear."
Eminem, one of the highest-selling rap artists of all time, known for his complex and controversial lyrics, admitted that the initial fame changed his behavior.
A friend told the Sunday Mirror that at one point Eminem was drinking a bottle of rum mixed with ecstasy and tablets of the painkiller Vicodin.
In fact, Eminem, 35, displays his affinity for the prescription painkiller as candidly as he does his love for his daughter, Hailie Jade; he has both images tattooed on his body.
"Hailie's birth was a wake-up call," Eminem told the Sunday Mirror. "She made me get … in gear, to make something of my life and try 10 quadrillion times harder than I had before. Everything I do is for her."
The 43-year-old is almost as famous for her rock star antics fueled by alcohol and drug abuse, as for her rock music. Though Love has not confirmed a painkiller addiction, painkillers have certainly made it on her list of recreational drugs.
