LINDSAY LOHAN at Cirque Lodge drug and alcohol rehab

LINDSAY LOHAN has entered the Cirque Lodge drug and alcohol rehab in Sundance, Utah, "The Insider" reports. According to sources within the facility, the 21-year-old star arrived over the weekend to begin an intense rehabilitation program that is expected to last a minimum of 30 days.

According to the Cirque Lodge Web site, upon check-in, a thorough mental and physical examination is completed.

For a price tag of $30,000 and up, the rehab offers privacy -- with rooms for 16 residents at a time. Rooms boast spectacular views, Jacuzzi tubs and private fireplaces, and stars such as MARY-KATE OLSEN and DAVID HASSELHOFF have reportedly sought treatment there.

Lindsay was previously being held for her own well-being in Los Angeles, in a safe place and far away from the paparazzi, according to Lohan family friend GINA GLICKMAN.

The 21-year-old is facing multiple charges: two misdemeanor charges of suspicion of driving under the influence and driving with a suspended license as well as two felony charges of possession of a controlled substance and bringing contraband into a custody facility.
