Ashley Greene's bloodsucking role in the Twilight saga has got her lusting after vampires in real-life.

The sexy star – and Maxim's current cover girl – reckons that mortals are no match for the undead when it comes to sex.

“Take the best sex you’ve ever had in your life, multiply it by 100 and that’s vampire sex,” said Ashley.

Well, they've had plenty of time to perfect their bedroom technique!

The actress recently revealed that playing Alice Cullen in the vampire series also re-awakened her passion for another physical activity - martial arts.

She said: “I'm definitely going to get more involved in it. When we were filming Eclipse we had fight training for about six weeks, so that kind of re-sparked that bug.

“I had a personal trainer on top of that and they had us do mixed martial arts fighting as well."
