The Spanish actress has turned to the Utah-born fashion queen, who has created one-of-a-kind designs for Nicole Kidman and Madonna, to design a fairytale dress for her.
A source tells In Touch magazine, "Penelope is working closely with L'Wren. Her dress will be one-of-a-kind and be accented with real pearls."
The actress is reportedly panning a wedding to fellow Oscar winner in their native Spain.
