The sexy star, 22, makes the steamy revelation in the new issue of Britain`s Fhm magazine, in which she poses near nude, holding up a satin sheet to cover her modesty. And in the accompanying interview, she admits her sexual appetite is insatiable. She says, "I have the libido of a teenage boy. I`d rather have sex all the time than leave the house."

I`m extraordinarily sexual within a monogamous relationship. Nothing is off-limits.

I`m just really confident sexually, and I think that sort of oozes out of my pores. It`s just there. It`s something I don`t have to turn on.
