The svelte star has just finished filming her role as Elizabeth Swann in the third Pirates movie At World's End but doesn't seem keen for another.

Keira told the film's producers a fourth film is out of the question, according to the Daily Mirror.

She said: "I've been playing this girl since I was 17. I'm 21 now and I'm on to very different things."

But it's not all bad news, as co-star Johnny Depp has admitted he would play pirate Captain Jack Sparrow again.
