from JustJared.com: Mischa Barton models for a photoshoot at Circular Quay in Sydney on Monday.

The former The O.C star posed for the photographer in two different colorful outfits but barely cracked a smile during the whole shoot.

The 22-year-old actress’ last-minute inclusion to Australian Fashion week comes after organizers were forced to change their original plan to bring out 14-year-old Polish model Monika Jagaciak.
