LOS ANGELES - Playing the future Queen of England really does pay off.

British actress Camilla Luddington, who portrayed Kate Middleton in the Lifetime TV movie "William & Kate," has landed a meaty role on Showtime's racy series "Californication."

Luddington will take on the role of a nanny who hired by Charlie (Evan Handler) and Marcy (Pamela Adlon) in an eight-episode stint.

"Californication" stars David Duchovny as has-been novelist Hank Moody, who is struggling to revitalize his professional career while maintaining a good relationship with his ex-wife and teenage daughter.

Showtime renewed the veteran dark comedy for a fifth season in January. Hip-hop musician RZA will also be appearing as a rap mogul for whom Hank considers writing a movie.
