Selena Gomez And Demi Lovato: A Timeline Of Their Friendship

From 'Barney' to 'Ask Taylor' to silly selfies -- Selena and Demi have a lifetime of history.

    Demi checked into rehab in 2010, and a few years later she gave an interview revealing the friends who were most supportive while she was healing: “Nick especially — he’s always been there for me. And Selena because she called me crying when I was in there and was just so worried,” Demi said. “I was like, ‘Look, I should be the one crying, it’s all good!’ But she was so worried and ever since then we’ve gotten closer.”
