Keira Knightley is refusing to star in any more Pirate Of The Caribbean sequels, insisting the third movie will be her last in the swashbuckling franchise.

The 22-year-old beauty made the announcement after finishing filming Pirates Of The Caribbean: At Worlds End, which will be released next year.

Knightley has played the part of cabin girl Elizabeth Swann since 2003's Pirates of the Caribbean: The Curse of the Black Pearl.

The British actress says, "I've been playing this girl since I was 17."

"I'm 21 now and I'm onto very different things."
