LOS ANGELES, Calif. -- Megan Fox has been called "Earth's Hottest Girl" and the actress' heat will only continue to rise with the release of this summer's "Transformers: Revenge of the Fallen," which she promises will have "twice the budget, twice the explosives, and twice the robots and fight sequences. It's a big, huge movie!"

But the actress' movies might be the third most talked about thing when it comes to Megan's life - right behind her dating life and her body.

In an interview in ELLE magazine's June issue, the young actress revealed how her much talked about relationship with Brian Austin Green began.

She first met Brian on the set of "Hope & Faith," saying he seemed "sweet and quiet, harmless. I was like, 'Oh my God, I have to be with you. You're not a threat, you're not some d-bag that's going to cause a lot of problems.'"

At the time Brian was 30, while Megan was just 18 years old.

"I had to convince him that I was slightly more responsible and well-spoken and had other things to bring to the table besides being 18," she told the mag.

Megan refused to comment on reports that the two have ended their engagement and are in couple's therapy.

"I do not want to comment on my relationship, period," she explained to the mag. "It's private. It doesn't belong to the world. It's mine. It's Brian's. It's not for other people to judge and talk about and write about in In Touch Weekly."

She also shot down the notion that her sudden rise to fame had somehow emasculated Brian.

"He doesn't want to be my date... he's a man. He has an ego. He went through this already, and he doesn't want it back - It was horrible. So he has sympathy," she said of the "Terminator: The Sarah Connor Chronicles" star. "He's the one person that I know that if I'm struggling and everything's getting crazy, I can call."

Megan might be remaining mum on the state of her relationship to Brian, but she's quick to shoot down rumors that she rebounded with "Twilight" star Robert Pattinson.

"I just randomly asked someone for a light and it was him. That was the extent of our 'relationship,'" she said of the brooding vampire star. "But I'm sure there's going to be a different guy every week now."

And Megan would like the world to know that Pattison is not her type anyway - the same goes for Zac Efron.

"He and Zac-- they're just too pretty with the big hair and the suits. And Rob is, what, 22? Zac is 21? That's a joke," Megan said. "Boys in their twenties are a waste of time. They have nothing to offer conversationally; they're immature. I feel like I have a better shot with someone in his thirties."

And though Megan is just 23, the actress tried to create the body of a much older woman for her role in Diablo Cody's upcoming horror movie, "Jennifer's Body," - the body of an almost dead woman.

"I decided I would turn myself into a zombie," she said of her body, which dwindled down to just 99 pounds while shooting the film that is due out in September. "I got super, super skinny, stayed out of the sun for four months, and got to where I was losing my eyelashes and my eyebrows."

But fans won't see a frail Megan when she battles robots with Shia LaBeouf this summer in "Transformers." She had strict orders from director Michael Bay to bulk up by adding 10 pounds and to bust out the bronzer.

"Mike doesn't want this little wispy, tiny girl to be the lead in his movie. He wants you to be substantial," she said. "[And,] he wants us to be, like, Brazilian! My foundation from the movie is the same color that they use on Jada Pinkett Smith."

Adding, "We just look red. Not even orange - we're, like, maroon!"
