Demi Lovato and Selena Gomez's Complicated Friendship Has Never Been Short on Drama

2010: Demi was the first one to hint that her friendship with Selena was on the outs when a fan asked her how Selena was doing and she responded, "Ask Taylor." That same year, Demi appeared in Girl's Life, where she spoke candidly about the status of their friendship . . . sort of. "We're both busy, and I wish the best for her," she said. "True friends don't let their friends or family be mean to you. If you can't trust somebody, you can't be friends with them."
