Megan Fox covers the mega sexy cover of October 2009 issue of Rolling Stone magazine. Inside, the Transformers hottie talks about her eating disorder, insecurities and how she’s going to eventually murder Brian Austin Green. More pics after the jump!

On cutting herself:
“Yeah, but I don’t want to elaborate. I would never call myself a cutter. Girls go through different phases when they’re growing up, when they’re miserable and do different things, whether it’s an eating disorder or they dabble in cutting.”

On if she had an eating disorder:
“If I did talk about it, I’d be taking on a role-model status, and I’d have to choose my words very carefully, and I’d have to make sure I reveal it in a specific way, and I don’t want to do it.”

On her insecurities:
“I’m really insecure about everything. Self-loathing doesn’t keep me from being happy. But that doesn’t mean I don’t struggle. I am very vulnerable. But I can be aggressive, hurtful, domineering and selfish, too. I’m emotionally unpredictable and all over the place. I’m a control freak.”

On how she’s going to eventually murder Brian Austin Green:
“I’ve had to say to Brian, ‘You have to go and stop talking to me, because I’m going to kill you. I’m going to stab you with something. Please leave. I’d never own a gun for that reason. I wouldn’t shoot to kill. But I would shoot him in the leg, for sure.”
