(Cover) - EN Showbiz - Marion Cotillard hates filming sex scenes.

The Oscar-winning actress says she's gripped with anxiety whenever she's called on set to disrobe.

And often times she finds herself fighting back tears.

"I am shaking; I feel very bad and I want to cry most of the time because I hate it so much," she told Britain's Daily Telegraph.

The 37-year-old star recently had to undress for her movie Little White Lies.

The French drama follows a group of friends who take a summer trip together. But their holiday is blighted by an accident, revealling their most intimate secrets.

And although Marion doesn't share the same adventurous approach to sex as her character, Marie, she is able to have a laugh at her carefree onscreen persona.

"I've never slept with the entire city like she does boys, girls, I mean, I had my experience but not like, Woo hoo! Party! Sex time!'" she mused to Marie Claire. (C) Cover Media
