The Friends star had a very public battle with addiction, going to rehab in 1997 and 2001 for drug and alcohol addiction and heading to the hospital in 2000 for alcohol-related pancreatitis – all at the height of his show's popularity. "It was terrifying," said Friends executive producer Marta Kauffman, "watching someone you care about in so much pain." In 2011, he returned to rehab for a short time to "focus on my sobriety and to continue my life in recovery," he said.
