Demi Moore's rehab location stays under wraps

When Lindsay Lohan attended rehab, the names of the treatment facilities almost always hit the media. It seems that Demi Moore, on the other hand, has learned the secret of keeping her whereabouts completely unknown.

After ducking the paparazzi on her way to the facility, Moore hasn't been seen since the incident with nitrous oxide put her in the hospital and her reps announced that she'd be seeking treatment for substance abuse (er... exhaustion).

People reports that Utah residents suggest she's headed to Cirque Lodge in Sundance, and that other rumors imply that she is holed up at her home in Hollywood having prayer sessions with estranged husband Ashton Kutcher.

"Demi is such a private person," says a source, "and where she is now is being kept top secret."
