Although the `Friends with Benefits` star doesn`t see herself as a sex symbol, she puts as much effort as possible into intimate scenes, because she hates it when actresses don`t make them convincing.

She said: "I`m not good at sexy. But there are so many women on the big screen who are so false you just don`t buy it.

"There`s nothing about them that you believe. It feels so put on. You can feel them mugging for the camera.

"It`s like their face is raping me, so I know I don`t want to do that."

Mila, 28, is also famously down to earth in real life, which she attributes to her upbringing to a poor family in the US, after her mother and father moved from the Soviet Union when she was seven.

She added to The Times newspaper: "I`ve been doing this [acting] since I was nine. It didn`t happen overnight, so I like to think I`m not in a bubble. I live a very normal life.

"My two best friends: one`s a dentist, one`s a teacher. We talk every single day. They`re not in this industry, we all grew up poor, we all fully understand the value of a dollar."

Mila added she has also seen the perils of fame first hand, and knows how Hollywood can go to some star`s heads.

She said: "I`ve seen it eat people alive. It happens often. I think people lose sight of themselves because of what they do. What I do is not who I am."
