Tatum O'Neal's rep said rumors about the actress entering rehab because of a cocaine problem are false and that O'Neal had some back issues and went to a treatment facility to titrate off pain medication that was prescribed for her back.

RadarOnline reported that an unnamed source said that O'Neal, 48, voluntarily checked into rehab because she suffered a cocaine relapse.

The story is untrue, O'Neal's spokesperson noted in a statement to OnTheRedCarpet.com. Tatum O'Neal had back issues, had back surgery and went to a treatment facility to titrate off pain medication prescribed for her back. The story about a cocaine addiction is false.

O'Neal won an Oscar in 1974 for Paper Moon. She has long battled drugs and alcohol addiction and her younger brother Redmond O'Neal has similar problems. O'Neal chronicled her history of substance abuse in her 2004 autobiography A Paper Life. The substance issue in her youth was reportedly because of her troubled relationships with her parents.

O'Neal later developed an addiction to heroin, according to OnTheRedCarpet.com. Reports are that she was arrested in New York City in 2008 for buying crack cocaine outside of her home. O'Neal pleaded guilty to disorderly conduct and agreed to complete a drug treatment program.

It is because of her history of substance abuse why O'Neal's rep said the actress is seeking help managing her pain medication for the back problems.

The rep told E! News that O'Neal went to a place so that her use of prescribe pain killers could be supervised until the pain had subsided.

She will always seek supervision when taking prescription medication that has addictive potential, the rep said.
