Sexy Jessica Simpson is stepping out of Daisy Duke’s skimpy hotpants — and into Pamela Anderson’s red one-piece.

The actress has landed the key role in the Hollywood remake of the 1990s TV show "Baywatch."

A source said: “Jessica really caught the eye in 'The Dukes of Hazzard' film last summer. She was the unanimous choice for the 'Baywatch' role.”

Jessica, 25, will play a heroic lifeguard on Venice Beach, Calif. — and may even copy the slow-motion running that made fellas such a fan of 38-year-old Pammi in the Saturday evening show.

The source added: “Jessica has all the assets to make Pammi’s part her own.”
