The "Piano Man" has had many stints in rehab and alcohol fueled driving infractions over the years. His latest stay at the Betty Ford Center in 2005 appeared to do the trick and he's been on the straight and narrow ever since.
Check out which other stars aren't strangers to partying.
Drew is likely the best story of a wild child cleaning up her act. She has been open about smoking marijuana by age 12 and snorting cocaine at age 13. By her late teens, she stripped down for magazines like Playboy, but her drug days were behind her.
Okay, so she's not exactly a reformed partier just yet, but there's always hope...
The "Parks and Recreation" star fondly remembers his early days partying with the brat pack. “We competed to see who could play harder, then show up for work and still kick a–,” he has said. But unfortunately, he was competing with heavy hitters. When asked who would win, he replied, “Charlie [Sheen] by a nose.”
Jack & Kelly Osbourne
It can't be easy to have Ozzy Osbourne as your dad! And although Kelly and Jack are both cleaned up and even successful now, they each struggled with drug use over the years.
"I had my tonsils taken out [at age 13], and they gave me liquid Vicodin," Kelly told People in 2009. "I found, when I take this, people like me. I'm having fun, I'm not getting picked on. It became a confidence thing." She went to rehab for her addiction to painkillers at 19 and 20.
While younger brother Jack also started partying as a tween, it was after his mom got diagnosed with colon cancer that he really spiraled out of control. "I had smoked pot and drank every day for two years," he told MTV. "I was taking Vicodin by the handful. Valium, Xanax, Dilaudid, Lorcet, Lortab, Percocet, you name it." By 17, he was in rehab.
The Black Eyed Peas singer has long been open about her year long stint with hard drugs.
"I got into a scene. I started going out and taking ecstasy," she recalls. "From ecstasy it went to crystal meth. With any drugs, everything is great at the beginning, and then slowly your life starts to spiral down. [I was] 90 pounds at one point."
She cleaned her life up after a drug-infused conversation with god and she's been sober ever since.
Robert Downey Jr.
The late '90s were a crazy ride for the "Iron Man" star. He dabbled in pills, drinking heavily and always pushing the boundary, even getting mixed up with opium and heroin. "Smoking dope and smoking coke, you are rendered defenseless," he later told Rolling Stone magazine. "The only way out of that hopeful state is intervention."
He has been clean since 2003 and credits his wife of seven years for helping him along the way. "There's no understanding for me of the bigger picture in real time in a hands-on way without her," he has said.
The actress didn't experiment (or at least hasn't openly discussed experimenting) with drugs, but she has said that she did other kinds of experimenting as a teen.
"My boyfriend broke up with me, and I decided that I was in love with this girl that worked at the Body Shop," she admits. "I decided that I was going to get her to love me back, and I went out of my way to create a relationship with this girl, a stripper named Nikita."
Megan has been in a heterosexual relationship with Brian Austin Green since 2004.
Charlie has battled with substance abuse for decades. In June 2012, he admitted to being drug-free, but alcohol is a different story.
"We live in a country where it's always Miller time," he smirks. "What are you gonna do? It's happy hour somewhere in the world."
Miller is better than tiger blood...
The heiress looked like she was going down the same path as LiLo for a while. In 2010 she pleaded guilty to drug possession after cops found her carrying cocaine in Las Vegas. But she has been keeping a pretty low profile with new boyfriend River Viiperi ever since.
When Mark Wahlberg is asked about a single moment that he would change in his past, it's quitting school when he was just 13.
"I would probably choose not quitting school because that's when everything started to go downhill. That's when the drugs and the violence and all that stuff started to happen," he says.
Meeting his wife Rhea Durham in 2001 turned his life around. "Obviously when I was going to have a child, it was like, you can't be a child having a child," he explains. The couple now has four kids.
In Dec. 2006 Nicole was arrested for failing a sobriety test after apparently driving the wrong way on a freeway in California. But that wasn't by far Nicole's lowest moment. "By 18 I had stopped using cocaine and that's when I got -- got into pills a little bit and then -- and then I got into heroin," she recalls. When she hit rock bottom she voluntarily went to rehab which she called "horrible" at first.
Now, the mom of two appears to be at a good weight, free from substance abuse and happy.
The rapper has not been shy about his love-hate relationship with drugs and raps about it in countless songs. When asked what he was recovering from when he titled his 2010 album "Recovery" the rapper replied: "Vicodin, Valium and Ambien, and toward the end, which caused my overdose, methadone. I didn’t know it was methadone. I used to get pills wherever I could. I was just taking anything that anybody was giving to me."
In 2009 the "Full House" alum chronicled her partying days with a book called "unSweetined" where she writes about her downward spiral after "Full House" and subsequent recovery.
“At the time I started doing the hard drugs, the methamphetamine and coke and stuff, it was a lot easier to hide than drinking,” Jodie explains.

The actor had a wild streak in his younger days and witnessed his brother River overdose on drugs in 1993. Luckily, Joaquin was able to live out a different fate and checked himself into rehab for alcoholism in 2005.
It's hard to believe that this former Goodwill ambassador for the United Nations was ever a wild child. She has admitted to being a cutter and experimenting with drugs when she was young. "For some reason, the ritual of having cut myself and feeling the pain, maybe feeling alive, feeling some kind of release, it was somehow therapeutic to me," she has said. The mom of six has also admitted to trying "just about every drug possible" at one time or another.
Celebs with wild and crazy pasts.
