Several of Hollywood's biggest stars have been candid about their sobriety journeys over the years. Kelly Osbourne, who previously talked about being sober for six years, revealed in April 2021 that she had suffered a relapse and was working on next steps. "Not proud of it. But I am back on track," she wrote via Instagram at the time. Demi Lovato, who first entered rehab for drug and alcohol addiction in 2010, has used their experience to help others who may be struggling with similar problems.
