Megan Fox is on the cover of Rolling Stone the Oct. issue

The October issue of Rolling Stone features "Transformers" star Megan Fox on the cover showing off a black leotard with leather trim and a skin-revealing mesh column running from her neckline to her belly button.

In a candid interview, the actress said her current boyfriend Brian Austin Green is actually only the second boyfriend she's ever had. "I can never have sex with someone that I don't love, ever, ever, ever," she said. "The idea makes me sick. I've never even come close to having a one-night stand. I'd be terrified. I wouldn't enjoy anything about it. I'm not sexually promiscuous. I've only been single for the seven-month period between my first boyfriend and the one I have now."

Though she continues to make frank statements about her personal life, Fox maintains that she's tired of having everything she says "sensationalized" and is constantly afraid that she's being made fun of by the media.

"I have a sick feeling of being mocked all the time," Fox confessed. "I have a lot of self-loathing."
