She has been hanging out in Sydney, Australia to promote her new movie “Hippie Hippie Shake” as of late, and earlier today (July 18) Sienna Miller was spotted grabbing some lunch.

The “Factory Girl” gal looked cute and casual as she made her way to Catalina restaurant, sporting a black shirt with stonewashed jeans and blue strappy heels.

Coming up this fall, Miss Miller will be starring in a Broadway production of “After Miss Julie” along with Jonny Lee Miller.  Preview performances begin September 18th, with the grand opening set for October 22nd.

Director Mark Brokaw explained, “Everything seems possible and all borders seem to have been potentially shattered.  It’s a story about a night that shouldn’t have happened but was destined to happen.”
