Just because Lovato was busy getting her life together doesn't mean she didn't make time to bicker with some of her Hollywood frenemies. In October, boyfriend-stealer Ashley Greene compared her beef with Lovato to that of Angelina Jolie and the sad and lonely Jennifer Aniston. Oh, please! They wish. Lovato also came out recently and said she and Miley Cyrus often go at it. "When we fight, it's brutal," she said before noting that they always kiss and makeup.
