LOS ANGELES: Demi Lovato cries all the time. The ‘Skyscraper’ singer - who checked into rehab in 2010 to seek help for self-harm, an eating disorder and drug and alcohol abuse - is an emotionally charged person who gets weepy at small things, such as a heartfelt compliment from her friend. She said: ‘’I’m so emotional. I cry all the time. One of my friends told me how proud she was of me and how I’ve come so far and that’s the last time I cried.’’ Demi, 21, also suffers from nerves and needed a little advice to calm her down before her ‘Neon Lights’ tour, which started this month.–EX
