Celebrity Rehab

Oscar De La Hoya is opening up about why he checked himself into rehab -- claiming he was abusing cocaine and alcohol, cheating on his wife ... and even considering suicide.

The boxing icon spoke with Univision -- saying, "There were drugs, my drug of choice was cocaine and alcohol. Cocaine was recent. The last 2 years, last 2-and-a-half years and I depended more on the alcohol than the cocaine."

De La Hoya says he's been sober for three months -- but he's still undergoing treatment. He also says he's joined Alcoholics Anonymous.

The boxer says he thought about killing himself, but ultimately decided he did not have "the strength" and "courage" to do it.

Oscar also revealed that he cheated on his wife -- explaining, "We are obviously not talking Tiger Woods here, but I was unfaithful."

One year after Eric Roberts completed a stint in "Celebrity Rehab" for weed "dependency," the actor is back on the pro-pot bandwagon ... releasing a new video in the hopes of legalizing the green stuff.

Back before he sought treatment last year, Eric's wife Eliza explained how the actor "quit drugs and alcohol in 1995" but still had an "interest in weed."

At the time, Eliza said, "He uses marijuana as a medication. He has a prescription ... however, a dependency is a dependency and he doesn't want to be dependent on it anymore."

Now, in a new video for TellDC.com, Eric is making the argument that if booze is legal, weed should be too ... saying, "Alcohol has destroyed whole civilizations whereas pot has only made a few hippies happy."

He adds, "Pot remains illegal because no one has figured out how to make it profitable for the government yet ... it's political, not protective."

So we gotta ask ...

TMZ has obtained the divorce papers, in which Justin Williams states that Kari Ann is pregnant -- and wants a judge to order genetic testing to determine if "this is a child of the marriage." The docs were filed in L.A. County Superior Court by Williams' lawyer Marlo Van Oorschot.

Kari Ann has been treated for sex addiction in the past -- even appearing on "Sex Rehab with Dr. Drew" back in 2009.

The couple has only been married for a few months -- they tied the knot back in February.

Jake -- Gary Busey's son -- was outside a Starbucks in Santa Monica, where he told us about the 21 "awesome" days he spent at a rehab facility ... and revealed that he's been sober for 42 days!

Warren's attorney -- Darren Kavinoky -- tells People.com, the "Planet of the Apes" star entered a residential treatment facility shortly after posting bail last month, and has been sporting the bracelet for the last 10 days.

Kavinoky adds, "She's committed to making the situation right and moving on in a way that's appropriate."

As TMZ first reported ... Estella was arrested May 23 -- after she slammed into three cars, kicked a cop and tried to escape from the police station. She was charged with DUI, hit-and-run driving, battery on a cop, and resisting arrest.

Melissa Binzer filed the divorce docs in L.A. County Superior Court recently -- citing irreconcilable differences.

But here's the interesting part -- they share a 7-year-old son, who has type 1 diabetes. Melissa claims Shifty has no idea how to take care of a diabetic child, so she's demanding full legal and physical custody.

On top of that, Melissa claims Shifty has struggled with drug and alcohol addictions for a long time, and she fears he "would not create a suitable environment" for their son.

Sambora told our photog at JFK he was feeling good -- which was evidenced by the fact he signed dozens upon dozens of autographs for fans.

He arrived from Los Angeles, but planned on heading right back out -- he's meeting up with Jon and the boys for the European leg of the tour. They are scheduled to play in Croatia on Wednesday.

Drew -- who treated Conaway on "Celebrity Rehab" -- tells us there is no evidence showing Jeff died from an overdose ... saying, "This was aspiration with overwhelming pneumonia and sepsis."

Drew tells us Jeff's condition was inevitable because the actor had been a serious pill popper for years and the constant substance abuse wore down his body.

Travolta adds, "My heartfelt thoughts are with his family and loved ones at this very difficult time.”

Conaway -- a notorious substance abuser -- had reportedly fallen into a coma after suffering an overdose earlier this month ... and doctors were not able to revive him.

Jeff's inner struggles became public when he appeared on "Celebrity Rehab with Dr. Drew" in 2008 and admitted to being addicted to cocaine, alcohol and painkillers.

Gary's 39-year-old son was on the boardwalk in Venice Beach yesterday ... when he explained how he woke up in an L.A. hospital this week after having "a little too much fun" with booze.

Vikki's best friend, Aubry Fisher, tells us the family members who blocked Vikki on Jeff's behalf last week don't have his best interests in mind because they refused to help him conquer his addictions in the past.

Conaway has been in a comatose state for weeks -- after he reportedly overdosed in his L.A. area home earlier this month.

We broke the story ... Oscar voluntarily checked himself into a treatment facility in California for substance abuse issues a few weeks ago.

Oscar has told friends he does not believe he hit bottom, but checked himself into rehab before things got totally out of control.

As one source put it ... Oscar has had fidelity issues and it seems to correlate with substance abuse ... and that's a matter he's dealing with in rehab.

As TMZ first reported, De La Hoya entered a rehab facility in California sometime within the last few weeks. We're told De La Hoya is seeking help for substance abuse issues. A source close to the boxing legend tells us he has "voluntarily commenced proactive treatment to address certain health and personal issues."

De La Hoya issued a statement to TMZ that reads, "After doing an honest evaluation of myself, I recognize that there are certain issues that I need to work on. Like everyone, I have my flaws, and I do not want to be one of those people that is afraid to admit and address those flaws.

"Throughout my career and my life, I have always met all challenges head-on, and this is no different. I am confident that with the support of my family and friends, I will become a stronger, healthier person.

We're told De La Hoya is seeking treatment for a substance abuse problem and checked into a California-area facility within the last few weeks.

De La Hoya has posted a flurry of very introspective tweets in the past few days, including, "Take a deep breathe and let out all that anger that makes you hate. it really is going to be o.k." and "Stop finding excuses not to live. life is controlled by what you make of it and not of what it makes of you."

Law enforcement tells us ... cops stopped Frankie for a routine traffic violation yesterday when they noticed an active warrant out for her arrest stemming from a probation violation.

We're told cops then performed a search -- and found "drug-related material" on her person.

Lons was arrested and transported to a nearby jail -- where she was booked for the probation violation and misdemeanor possession of drug-related material.
