Looking fiercely fit on the cover of Women's Health, Ashley Greene is showing off her rockin' bikini bod!

The Twilight star is certainly giving her co-star and Men's Health's cover-boy, Kellan Lutz, a run for his money.

Greene, 23, reveals her competitive edge when it comes to staying fit, telling the mag, “I’m a competitive little sucker. A lot of people like to be super tiny, but I don’t want a child’s body—I want a woman’s body that is extremely fit. It’s so much sexier.”

As for what Ash is looking for in a guy, she says, “I like a pretty boy with an edge. Someone who has blue eyes, who has mystery, and who’s a little brooding.”

Hmmm...sounds like Kellan to us!
