Jude Law's girlfriend Sienna Miller has become the face of denim fashion house Pepe Jeans London.

The Alfie actress signed a two-year contract after fashion bosses were seduced by her unique sense of style.

Pepe Jeans London boss CAROLS ORTEGA says, "We wanted a strong, positive, female British figure to head the advertising campaign, and strongly believe the choice of Sienna Miller was the right one."

The 24-year-old star's ad campaign debut has been shot by MIKAEL JANSSON and KARL TEMPLER in Paradise Cove, California.
