Actor Rob Lowe has put his wild past a quarter century behind him. The former member of the hard partying “Brat Pack” in the 1980s took to Twitter this weekend to share his major milestone along with a message of hope.

“To those struggling with addiction, there is true, real hope. 25 years ago today, I found recovery; and a life of promise. #Grateful” he wrote.

Lowe has come a long way since the '80s, when his involvement in a scandal involving a sex tape with an underage girl threatened to derail his acting career. Two years after the scandal, in 1991, he spent a month in rehab, which he describes in his 2011 memoir as "one of the most exhilarating, liberating and exciting four weeks of my life."

The actor, now 51, has been sober ever since. “[Getting sober] changed my life forever and everything good that I have is a result of that,” he told The Fix last summer. “It's not a struggle for me. I see people struggle with it. I luckily was not a person that needed to struggle. I was done.”

He has credited his wife, former Hollywood makeup artist Sheryl Berkoff, with helping him stay sober and salvage his career, calling her “the opposite of an enabler.” In the past 25 years, Lowe has gained notoriety with roles in network series like The West Wing and Parks and Recreation, won a Screen Actors Guild Award, and been nominated for multiple Golden Globes.
