'X Factor' Demi Lovato staying at sober living home?

The X Factor USA judge Demi Lovato is reportedly staying at a sober living home.

A source close to the 'Skyscraper' singer told TMZ that Lovato began spending time at the sober facility shortly after leaving rehab two years ago.

Lovato spent time in an in-patient rehab centre from October 2010 to February 2011 to cope with "emotional and physical issues", which she later revealed to be cutting and bulimia.

She has most recently served as a judge on The X Factor, apparently returning to the sober living home after each taping.

An insider claimed that Lovato is committed to maintaining a healthy state of mind and uses the sober living environment to cope with stress.

Lovato has not issued any formal comment on the matter.

The popstar did recently reflect on her past troubles in a New Year's Eve message to fans, where she wrote: "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. Recovery is a beautiful thing friends. Life is good, God is great!"
