The bird leaves the cage freely. Lindsay Lohan has completed her stint at rehab, leaving the drug and alcohol rehab center Promises in Malibu on Friday July 13th after a more than six weeks stay.

Lindsay's representative, Leslie Sloane Zelnick, released a statement on Sunday July 15th, saying "On Friday, July 13, 2007, Lindsay Lohan successfully completed her 45 days of residential and extended care treatment at Promises. She has transitioned to an intensive outpatient program, which includes attendance at daily AA meetings, outpatient therapy and daily testing."

Leslie Sloane Zelnick, moreover, went on saying that Lindsay "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."

Lindsay who left Promises shortly before down was, in fact, seen partying again over the weekend. The singer-actress was spotted at Pure Nightclub in Las Vegas on Saturday July 14th reportedly to attend the surprise birthday of her roommate/assistant, Jenny. Onlookers who were on the scene said to have seen Lindsay drinking Red Bulls and Voss water instead of beer and wine. "A lot of the attention was placed on Lindsay and she was smiling, really enjoying the evening," a clubgoer added.

Lindsay checked into the Promises treatment center in Malibu on May 28th following a DUI arrest the days before. This is the second time that the star underwent a stint in rehab. She had been attending Alcoholics Anonymous for about a year before.
