Is she finally serious about sobriety?
A source close to Lindsay Lohan’s says yes, that the actress, who has relapsed many times before, is getting a framework in place to keep her from falling into substance abuse again upon her latest release from rehab.
That means truly committing to therapy and AA, cutting enablers out of her life and leaning on good influences, including Oprah Winfrey, for support.
“She’s the best I’ve ever seen her, honestly,” the source tells PEOPLE. “All she wants to do is work.”
“She’s doing really, really well. She has a sober coach who’s going to be traveling with her and close to her in New York and is basically going to be assigned to her for an extended period of time.”
The source adds: “She’s got those three therapy sessions a week now that are court ordered. And on top of that, she’s going to AA meetings daily. So I think she’s going to do really well this time. I’ve never seen her commitment so strong.”
The Canyons actress, 27, is also trying to separate herself from enablers, the source close to her says. “She’s cut a lot of people out of her life She’s keeping her distance from her mother [Dina].”
Some of that is Oprah Winfrey’s influence, the source adds. Winfrey recently struck a deal to interview Lohan for a special in August and create an eight-part documentary series starring the actress, to air in 2014.
“I think a lot of it has to do with the Oprah people really supporting her and telling her what to do,” the source says of Lohan’s decision to surround herself with more positive people.
