Meanwhile, Scarlett Johansson branded actresses who sell personal stories "vulgar".

The 'Lost In Translation' star can't stand reading interviews with other female celebrities baring their souls about their love lives, addictions and eating disorders.

Scarlett told Glamour magazine: "I'll never sell my sob story to some magazine. I read those issues in which people are crying on a reporter's shoulder and the reporter writes, 'And then she started to sob…'

"All these stories in which these girls open up a little too much. It makes me go, 'Aaaagghh!' And then they talk about their bulimia, or their drug addiction. And I think, 'Why are you talking about this?' It's vulgar.' "

In other news, Scarlett Johansson is shocked and saddened by the racism that still exists in the world.

The Lost In Translation star is disappointed to discover prejudice wherever she travels.

She says, "People are still so racist. It amazed me - all over the world, not just here. I wonder if people are born with prejudice and we have to overcome it. Or is it, we're born without it and it's a learned thing?"
