Lindsay Lohan Leaves Rehab After 45 Days, Celebrates In Vegas

Actress unwinds by partying — soberly — at nightclub.

Lindsay Lohan checked out of Malibu, California's Promises rehab facility on Friday after more than six weeks, according to People magazine.

The actress celebrated the end of her 45-day stay by soberly partying with some friends at the Pure nightclub in Las Vegas on Saturday night (check out photos from Lohan's party right here). She'd been scheduled to hold her 21st birthday party at the club on July 2 (see "Lindsay Lohan Checks Into Rehab: Report").

A statement from her representative confirmed the release from rehab and gave a hint at Lohan's future plans. "On Friday, July 13, 2007, Lindsay Lohan successfully completed her 45 days of residential and extended-care treatment at Promises," read the statement, according to People. "She has transitioned to an intensive outpatient program, which includes attendance at daily AA meetings, outpatient therapy and daily testing. On her own, she has also made the decision in support of her sobriety to wear an alcohol-monitoring bracelet. 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."

"[Lohan is] doing great," said spokesperson Leslie Sloane Zelnick. "Lindsay is working hard on her sobriety, and we are all supporting her."

Lohan, wearing her alcohol-monitoring ankle bracelet, reportedly sipped nothing stronger than an energy drink while hanging out with 10 friends at Pure. "A lot of the attention was placed on Lindsay, and she was smiling, really enjoying the evening," a clubgoer said.

Lohan's second rehab stint this year came after a Memorial Day weekend car crash (see "Lindsay Lohan Arrested On Suspicion Of Driving Under Influence"). She smashed her Mercedes-Benz into a curb and was arrested on suspicion of driving under the influence — she was later photographed slumped over in the passenger seat of DJ friend Samantha Ronson's car.
