Hilary Is a Barbie Girl

Hilary Duff is designing outfits for the tiniest blonde in Hollywood--and we don't mean Nicole Richie.

The popstar has collaborated with Mattel to create a line of clothes for the most popular doll in the country, the one and only Barbie.

The collection features 11 outfits which include denim pieces, accessories and even faux fur. The ensembles are broken up into two categories, sweet and rocker, which "reflect Hilary's personal style."

This isn't Duff's first foray into the fashion biz. Hilary has a tween fashion label, Stuff by Hilary Duff, and earlier this year she guest edited an issue of Seventeen magazine.
