Demi Lovato battled Miley Cyrus in the championship of THG's Celebrity of 2011 Tournament, narrowly edging the singer/actress by .2% of the vote.

In the latest issue of Seventeen, meanwhile, Demi says our readers came up with the perfect title-round matchup, considering she and her fellow young star have always had a friendly, contentious relationship.

"Miley and I are very strong-headed, so when we fight, it's brutal and we're like, 'We're never going to be friends again!'" Lovato tells the magazine. "Then two days later, we're like, 'I love you and I miss you!'"

Aside from Cyrus, Demi opened up to the publication about other famous friends and how they reacted to her tumultuous year, which was lowlighted by a trip to rehab.

SELENA GOMEZ and her "never" fight, Lovato says: "She's not a confrontational person at all. Both [she and Miley] will never leave my life no matter what happens, because we've been through so much together."

TAYLOR SWIFT "Tweeted 'Pray for Demi,' which I thought was really awesome of her."

KIM KARDASHIAN called Lovato and "was there for me when not many people were. I could count on my hands how many people were there for me. So the people who were, I didn't forget it."
