Miley Cyrus (l) and Demi Lovato have a contentious relationship, Lovato says (X17 Online)X17 Online
Former Disney star Demi Lovato.
"(Miley) and I are strong headed. When we fight it's brutal and we're like, 'We're never going to be friends again!' Then two days later, were like, 'I love you and I miss you!'"
Lovato has been involved in several well-publicized spats with Cyrus, including an infamous video the “Party in the U.S.A.” singer posted to YouTube where she and a friend viciously mocked Lovato and fellow Disney star Selena Gomez.
Eventually, Cyrus apologized–sort of–and removed the video. “I mean if we offended (Gomez and Lovato), we’re super sorry, but we were, like, just having fun,” Cyrus said at the time. “Elvis says imitation is the greatest form of flattery, so we were imitating them being funny."
Now, all is forgiven.
"Both (Miley and Selena) will never leave my life no matter what happens, because we've been through so much together," Lovato told Seventeen.
Lovato, who entered rehab in November 2010, also revealed to Seventeen how she dealt with her adolescent angst.
"I'm not gonna lie. I was self-medicating," she said. "I was doing things like drinking and using [drugs], like a lot of teens do to numb their pain. (But now) I don't drink, I don't do drugs, I don't throw up after my meals, I don't starve myself. There's nothing that I do that I feel ashamed of."
