Lindsay Lohan has checked into the posh Cirque Lodge drug and alcohol rehab center in Sundance, Utah, reports say.

The 21-year-old starlet arrived this weekend to begin an intense rehabilitation program that is expected to last a minimum of 30 days, sources within the facility reportedly told "The Insider."

The Lodge was named by Town & Country magazine to be one of the country's top rehabs. Rooms cost $30,000 and up, have spectacular views, Jacuzzi tubs and private fireplaces and reportedly have been sought by Mary-Kate Olsen and David Hasselhoff.

Until this weekend, Lohan was in Los Angeles, family friend Gina Glickman told "The Insider."

The New York Post reported Sunday that Lohan had returned to her native Long Island, New York, to be with her mom and other family. She reportedly flew into Kennedy Airport with her sister Ali, 13.

"She's doing well," her mother Dina Lohan told the Post on Saturday.

The Post also cited conflicting reports on whether or not the troubled starlet had entered rehab after her July 24 arrest in Santa Monica for investigation of drunken driving and cocaine possession.

Sources said Lohan was spotted last Wednesday eating with sister Ali at Los Angeles eatery Koi.

TMZ.com reported Monday, however, that Lohan never returned to her family's New York home, saying a rep for the star said she never made it back there.

Lohan last entered rehab after she was arrested May 26 on suspicion of driving under the influence after crashing her car into a curb on Sunset Boulevard.

She entered the Promises Malibu Alcohol and Drug Rehab Treatment Facility and was released on July 13, after a stay of more than six weeks.

Less than two weeks later, she was arrested again. Lohan's arraignment is now set for Aug. 24.

Meanwhile, in an interview with Elle that the magazine says took place just 36 hours before her July 24 arrest, Lohan said she was “too responsible” to drink and drive. The issue featuring the interview hits stands Aug. 14.
