Demi Lovato has given up her cell phone as part of her healthy new lifestyle.

The singer-turned-TV talent show judge has battled numerous personal problems over the last few years and checked into rehab in 2010 to address issues including bipolar disorder, self-harming and an eating disorder.

Lovato has since landed a new job as a judge on America's "The X Factor" and embraced a healthy new lifestyle regime, which includes meditation and giving up her cell phone.

She tells America's Self magazine, "I make time for myself and meditate. I've spent the past two years getting over an eating disorder and issues like self-harming and bipolar disorder. I have to work on this stuff every day. I'm reminded of that whenever I eat or feel down..."

"I haven't used my cell (phone) in three months! Subconsciously, it was a crutch. When a room gets quiet, what do you do? Grab your phone! Now I can sit and have conversations with people."

Lovato goes on to reveal she turned to self-harming to deal with crippling bouts of anxiety, explaining, "There were times I felt so anxious, almost like I was crawling out of my skin - that if I didn't do something physical to match the way I felt inside, I would explode. I cut myself to take my mind off that. I just didn't care what happened. I had no fear."
