The 26 year-old star checked herself into the Timberline Knolls rehab center near Chicago in January due to suffering from an undisclosed eating disorder, reported Contactmusic.
"It(Rehab) was the scariest thing I've ever done and in hindsight, it saved my life. I'm in an industry where people photograph your body and zoom in and blow it up and put it on the cover of magazines, and other people make terrible comments.
"My eating disorder is something I've been struggling with for a while. People will make up stories, but I went to rehab for an eating disorder-nothing more and nothing less," she said.
"My whole message is to love who you are and accept all your beautiful imperfections. When I felt I was slipping into unloving territory with myself, I knew I had to listen to my own advice and correct it," she added.
