Pirate Beauty Back for More Booty

Sultry Keira Knightley is finally back where she belongs ... hitting the high seas as Elizabeth Swann on the set of "Pirates of the Caribbean 3."

Cameras spotted the British beauty catching a ride on a small transfer boat as she made her way to the Black Pearl. The massive floating set is currently drifting off the coast of Long Beach, Calif. Despite roasting in the blazing California sun, Keira was all smiles in her Asian-influenced costume.

The third installment of the Pirates series will attempt to swashbuckle its way past the $1 billion mark set by its predecessor when it hits theaters next May.
