Melanie Griffith, 43, said in a written statement released yesterday — signed, “With love, Melanie” — that she has entered a hospital for treatment of a drug problem. “My doctor has referred me to the Daniel Freeman Hospital to step down from the prescribed medication that I have been taking for a neck injury,” she said. The “Working Girl” Oscar nominee, whose husband is Antonio Banderas (her fourth marriage, after she married Don Johnson twice), did not specify the nature or ramifications of the injury, the type of medication or how long she has been on it. “I appreciate everyone’s concern and I’m sure that you will respect my and my family’s privacy.” In the late ’70s and early ’80s, reported PEOPLE, Griffith was addicted to drugs and alcohol, which made her persona non grata with movie studios. In 1980, she suffered a broken leg and arm when she was hit by a car while she was crossing Sunset Blvd. — but her doctor said that if she hadn’t been drunk she probably would have been killed. In 1988 she checked into the Hazelton Clinic for rehab. A hospital spokeswoman would not comment to Reuters on Griffith’s current treatment, other than to note that patients at the nonprofit Catholic facility in the beach section of Los Angeles usually follow a 12-step program that includes time devoted to fellowship and reading.
