Lindsay Lohan has left a Malibu rehab center after a stay of more than six weeks.
The "Mean Girls" star, who turned 21 on July 2, left Promises Malibu Alcohol and Drug Rehab Treatment Facility on Friday, according to a report on People magazine's Web site Sunday.
She will voluntarily wear an alcohol-detecting ankle bracelet as part of an intensive outpatient program, said her publicist, Leslie Sloane Zelnik, in a statement.
On Saturday, Lohan was reportedly seen partying at Pure Nightclub in Las Vegas with several friends.
"In part she is wearing the bracelet so there are no questions about her sobriety if she chooses to go dancing or dining in a place where alcohol is served," Zelnik said.
Lohan checked into the swank facility after a wild Memorial Day holiday weekend in late May during which she crashed her Mercedes Benz into a curb, was arrested on suspicion of driving under the influence and was photographed slumped in the passenger seat of a friend's car.
Her outpatient program includes going to Alcoholics Anonymous meetings, taking daily tests and receiving therapy.
"She's doing great," Zelnik said. "Lindsay is working hard on her sobriety and we are all supporting her."
It was the star's second stint in rehab this year. She said in January she had checked into a rehabilitation center for substance abuse treatment.
