SPOTTED: Demi Lovato at The Grove in Los Angeles on October 11, 2011 for an interview with Extra‘s Mario Lopez.

Demi, who is happy and healthy for the first time in a long time, is ready to get back on stage when her Unbroken tour takes off November 16, 2011 in Detroit. Her new tune, Skyscraper, is a “song about rising above your problems and …is supposed to inspire people,” Lovato said.

Lovato, who publicly battled bulimia and was involved in cutting herself, recently finished a three-month-long stint at a treatment facility. She said sharing her past ordeals is not only therapeutic for her, but it also lets her inspire people in similar situations to get help. “When you go through something like this,” Lovato said, “you really find out who your true friends are and [Kim Kardashian and Selena Gomez] were really there for me.”
