Megan Fox W Magazine March 2010

Megan Fox graces the upcoming cover of W Magazine, on newsstands Feb. 23.

The 23-year-old actress who is engaged to actor Brian Austin Green, says she is a very maternal person but she doubts she will have kids.

"No-one believes me when I talk about this, but I'm really maternal. I worry that because I've always wanted kids so much, as the world goes sometimes, I won't be able to have them - even though I would be able to provide them with such an amazing environment."

Here's more:

On posing in underwear for Emporio Armani: "..There are some women you could put in underwear and photograph them, and it looks really classy and it doesn't necessarily provoke a pin-up image. But with me it does, immediately, as soon as I'm in underwear. I'm a Vargas Girl."

On being a fashion icon: "Being super fashion-forward and always stepping out in the latest whatever is out there, being a constant fashion plate, like a Rihanna or whoever-that, to me, seems exhausting."

On trusting her Hollywood colleagues: "I don't trust people in this industry, but I especially don't trust girls in this industry, because it's incredibly competitive, and I'm just not interested."
