"I couldn't have gotten sober without rehab," the 50-year-old star told Oprah. "Because I needed the science. I needed to go to the college of addiction, and what it does to your body, and all of the research… A lot of people can do it through 12-step programs alone, I wouldn't have been one of them. Although I believe in that too. I needed to do the work."
