Megan Fox is known for films filled with explosions – but at home, she says she's the one responsible for the property damage.
"I'm emotionally unpredictable and all over the place. I'm a control freak," the star told the October issue of Rolling Stone. "My temper is ridiculously bad. I've destroyed the house."
So bad, she explained, that she's had to tell on-again/off-again ex-fiance Brian Austin Green to give her some space – or else.
"I go bats**t. 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,'" she said. "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."
Still, the volatile star said she's not an unhappy person.
"Self-loathing doesn't keep me from being happy," Megan said. "I have a lot of things to be happy about. But that doesn't mean I don't struggle. I am very vulnerable."
Among her fears, despite her title role in horror romp "Jennifer's Body," out this Friday, is the dark.
"I'm afraid of the dark and can't sleep without it," she told the mag. "Yeah. If there's silence and darkness, I can't sleep."
And while the film finds her starring as a demon-possessed high schooler who has to eat boys to survive, she said it was a kissing scene with female co-star Amanda Seyfried that she found the scariest.
"Amanda was not excited about having to do it, but I went for it," she recalled. "Clearly I can't argue that it's not gratuitous, because it is. We both look like children, so it looks like crazy kiddie porn. There's no music – it's just silence and the sound of spit. I feel weird watching it. It was just really uncomfortable. I felt like I was witnessing something I'm not meant to see."
