9 Celeb Couples Who Fought Addiction Together

When these celebrities faced a struggle with addiction, their partners stood behind them. Wonderwall rounds up nine famous couples who weathered the storm together:

• Melanie Griffith has been treated for substance abuse problems three times, two of them during her relationship with Antonio Banderas. She's written on her website about how much his support helped her.
• Robert Downey Jr. struggled with addiction for many years, and he gives wife Susan Downey credit for his sobriety. "[She] has got me in a freakin' choke chain, and I love it," he once said.

• Michael J. Fox developed a drinking problem after being diagnosed with Parkinson's disease. "This was the first time I was drinking in order not to feel something. It had a dark purpose," he said afterward. Wife Tracy Pollan helped him get sober.
• Matthew Perry has been dating Lizzy Caplan since 2006, and she stuck by his side during his third stint in rehab in 2011.
