In 2010, Demi Lovato went to rehab for drug and alcohol abuse, along with an eating disorder and cutting. A year later, she left and focused on her personal struggles and also being a positive role model to her sister, along with her fans. Lovato says that her family saved her life by ensuring she went to rehab, and we are so glad she’s four years sober and strong. Lovato has been up to a lot lately, including an amazing and affordable makeup line (Naked dupe, anyone?) with New York Color, along with releasing new music.
