Located in Sundance, Utah, it's no wonder the Cirque Lodge has attracted so many famous clients. Demi Moore has just checked into the facility for treatment after a hospitalization in January and she isn't the only spotlight celebrity to be admitted. Charlie Sheen's ex-wife Brooke Mueller is also undergoing treatment at the rehab center, according to Radar.

She hasn't had any interaction with other patients yet, a source told Radar referring to Moore. She is still in detox at the moment.

Moore is expected to stay at Cirque Lodge for 30 days, while Mueller is set to check out at the end of the month.

Miley Cyrus also quickly came to the 49-year-old actress' defense, advising media and critics to leave Demi alone.

She's been through so much in the past year, Cyrus wrote on her Facebook page. She doesn't need the crap. How can you talk crap on someone you don't know?

Cyrus, who will be starring in the film LOL alongside Moore, continued to aid her co-star, saying that her health issues are not substance related.

The media makes everyone in Hollywood seem 'weak,' 'stupid' or 'unbalanced'...Just because she's in Hollywood doesn't mean she's on drugs. NOT EVERYONE IS ON DRUGS!!!

The rustic lodge, complete with its own recording studio on site, has been home to many other stars during their time of need. Mary Kate Olsen, Eva Mendes, and Kirsten Dunst are a few of the lodge's previous guests.
