The young star is so committed to maintaining her hard-earned health that she’s been living in a sober house for over a year, according to People.

“She’s very smart,” a source told the mag of Demi’s decision to rent a room in the sober house, instead of residing in her Los Angeles home. “She takes whatever steps she needs to make sure she stays healthy.”

Demi – who went to rehab for eating disorders and cutting in late 2010 – even stayed at the sober house during her stint as a judge on “The X Factor’s” second season, the mag reported.

In addition to her living situation, the “Give Your Heart A Break” singer continues to speak out about the blessing of recovery.

On New Year’s Eve, Demi took to Twitter to reflect on her painful — but worthwhile — journey to health.

“Two years ago, I watched the ball drop on TV in rehab and cried my eyes out. Tonight I’m on the beach with my closest, most loyal friends sipping coffee and sharing how beautiful life is and how far we’ve come,” she shared with her 11.4 million followers. “Recovery is a beautiful thing friends.. Life is good, God is great!”
