Selena Gomez, Demi Lovato's on-off close friend from their Barney and Disney days, posted a heartfelt public message to Lovato last night after Lovato's Grammys performance of "Anyone." Lovato said ahead of the ceremony that she recorded "Anyone" days before she was hospitalized for a drug overdose. The song was what Lovato saw as a call for help during that time of her life, she told Zane Lowe on Apple Music's New Music Daily program.
