(Cover) - EN Showbiz - Natalie Portman insists her work isn't that important, because if she messes up, "no-one dies".

The stunning actress is one of Hollywood's hottest stars, having received a host of awards for her lead performance in dark thriller Black Swan.

Although she puts pressure on herself to do well, the 30-year-old knows that failure isn't the end of the world.

"I go between confidence and insecurity all the time. I think I won't be able to do something, but I'll do it anyway, because I know that failing isn't that bad," she told Psychologies magazine.

"With my job, if I mess up, no-one dies."

Although she has enjoyed a glittering film career, Natalie insists that she has endured harsh criticism. However, she refuses to let any negativity get her down.

"I didn't get down on myself. I'm the type of person who takes criticism as a challenge to push myself harder and aim higher," she added. (C) Cover Media
