Lindsay Lohan has checked out of a drug and alcohol treatment program in Utah that she entered in August, People magazine said.
Lohan, 21, left the Cirque Lodge treatment center Friday, the magazine reported on its Web site, citing statements from her parents.
"I'm proud of her. She's moving ahead with her life," her mother, Dina, told People Friday. "Things were getting out of control. She took action. She took responsibility. She really needed to heal."
The exclusive center, which promises anonymity to clients, refused Saturday to confirm or deny the report. Calls to Lohan's publicist and attorney were not immediately returned.
Lohan's visit to the Sundance-based Cirque Lodge was her third trip to rehab since January, a frenetic year in which she wrecked a Mercedes-Benz, released the box-office flop "I Know Who Killed Me" and was arrested more than once.
Lohan has been prominently in the public eye since becoming a star at 11 in the Disney film "The Parent Trap." She's also appeared in "Mean Girls," "Freaky Friday," "Herbie Fully Loaded" and numerous other films. In recent years, however, she's become better known for nonstop appearances on the Hollywood nightclub scene.
"Now that she is going out into the world, I can only hope for the best," her father, Michael Lohan, told People.
In May, Lohan was arrested after crashing her Mercedes-Benz into a tree in Beverly Hills. She was arrested again in July after the mother of Lohan's former personal assistant called 911 to report that her car was being chased by an SUV. The chase ended in Santa Monica, where police arrested Lohan for being behind the wheel.
In both cases, Lohan was found in possession of small amounts of cocaine.
In August, she reached a plea deal on misdemeanor drunken driving and cocaine charges stemming from the arrests. The deal called for her to enter treatment, spend a day in jail and perform community service.
"It is clear to me that my life has become completely unmanageable because I am addicted to alcohol and drugs," Lohan said in a statement released by her publicist last August.
