Washington - If there's one skill that Keira Knightley hasn't mastered as yet, it would be the art of cooking.

The British beauty confesses that she is utterly "hopeless" in the kitchen. So much so, that she even encourages her friends not to try out anything she rustles up, for she fears that they might end up getting food poisoning.

"I have tried but I really am hopeless," Contactmusic quoted her, as saying.

"I can cook maybe one dish but even then, if you ate it, you'd probably end up with food poisoning," she added.

The actress can currently be seen on the big screen opposite heart-throbs Johnny Depp and Orlando Bloom in the final movie of the 'Pirates of the Caribbean' trilogy 'At World's End'.

The Oscar nominated actress returns as the aristocratic Elizabeth Swann.

And while she certainly has a special place in her heart for her 'Pirates' role, Knightley recently revealed that she was "relieved" that she was moving on from the movie.

"This is such a relief. Not that I don't enjoy all that Pirates stuff, but it's not about my character - it's about Johnny (Depp)'s character. It's not focusing on emotional turmoil. It's been great just to get my brain engaged," Contactmusic quoted her, as saying.
