When Gossip Girl star Jessica Szohr turned up at a Louis Vuitton party, we got our first glimpse of Hilary Duff’s new Femme for DKNY Jeans line.

Szohr sported a $59 floral cardigan from the collection. Now the ads are out, starring Hilary (who will be guest starring on Gossip Girl this season) alongside models Sophie Srej and Gracie Carvalho in a NYC street-inspired campaign.

Combining Hilary’s personal style and the individuality of New York - the inspiration behind her designs - the Femme for DKNY Jeans fall '09 ads were shot on the Manhattan streets by Scott Schuman, of the style blog The Sartorialist.

With Hilary Duff joining the NYC-set series this fall, what better theme than the gritty and glam streets of the Big Apple for her latest venture?
