Hilary Duff has added doll clothing designer to her impressive resume after being asked to create a new line for Barbies in Japan. The pop star/actress and sister Haylie, both huge Barbie fans, have been asked by toymaker Mattel to design a mini-wardrobe for their Japanese likenesses.

Hilary says, "Barbies have really cool couture clothes in Japan... They made Barbies of Haylie and I and we got to design the clothes and it was really cool. (Asian designer) Anna Sui has a Barbie doll and all these designer clothes so we felt special."
