Singer Joss Stone is joining the cast of Showtime's THE TUDORS in a significant role alongside Jonathan Rhys Meyers.

Stone will play Anne of Cleves, the fourth wife of Henry VIII (Rhys Meyers).

A daughter of a German nobleman, Anne was betrothed to Henry in a marriage treaty between the Cleves Court and the king's chancellor after Henry was shown a portrait of her.

Upon Anne's arrival to England, Henry was disappointed in her looks and soon found a legal way to have the marriage annulled.
