Keira Knightley was more than comfortable going topless in her new movie - because she does it in most of her films.

The 23-year-old actress was happy bearing her bosoms in new film ‘The Edge Of Love’ because she hates it when people appear in big screen sex scenes with their underwear on.

She tells People magazine, “I always bare my breasts. It's not like it's only in this film!

"It was very simple. It was a sex scene and I never like them when they've got bras on."
