Ozzy and Sharon Osbourne announced during their live appearance on CNN's "Larry King Live" Friday night that their 19-year-old daughter Kelly has entered the Promises drug and alcohol rehabilitation center in Malibu, California to treat an addiction to painkillers.According to Sharon, her publicist received a phone call from a British tabloid Friday morning asking for comment on a photo showing Kelly doing a drug deal. Sharon then confronted her daughter, who at first denied doing drugs. "Being a drug addict and alcoholic myself, I know telling the truth doesn't come easy," Ozzy said. "It's a family illness. It's in the genes. In this day and age, the availability of getting drugs is amazing." "I can't believe we were buying into it," he said. "The amount of pills I found in her bag was astounding." Sharon said that Jack Osbourne brought his sister to the rehab facility on Friday. A year ago, Jack checked into Las Encinas Hospital in Pasadena, California for an addiction to the painkiller OxyContin as well as marijuana and alcohol. Kelly has spent the past few weeks writing material for her next album as well as shooting an ABC pilot.
