According to an E! News insider, the troubled actress - who was rushed to the hospital on January 23 for “smoking something,” based on the 911 call placed on her behalf - has checked in to Cirque Lodge, an expensive treatment facility in Sundance, Utah. Radar Online says:

Ashton Kutcher’s estranged wife began her treatment at Cirque Lodge several days ago, a source tells E!

It’s expected she’ll be there at least 30 days.

The drug and alcohol treatment center overlooking the Sundance ski resort is a celeb favorite. Mary-Kate Olsen [and] Lindsay Lohan [were both] treated there.

And what resounding successes those two gals are. Mary-Kate Olsen has clearly conquered her anorexia and Lindsay Lohan is the very picture of sobriety these days. Forty grand might seem like a lot of money, but with an impressive track record like that, I think we can all agree it’s money well-spent. They’ll have Demi cured in no time.
