Kristen Stewart wore Chaiken to link up with Chris Hemsworth for a scenic Snow White and the Huntsman photo shoot in Sydney yesterday. They struck a series of poses indoors, then Kristen nabbed a seat with a good view of the city's Opera House. Kristen premiered SWATH in Australia last night in a green, embroidered Balmain ensemble. She's Down Under with Chris on their latest promotional tour, but back in the US, Twilight fans are getting excited about one of her next pictures hitting the big screen. The new Breaking Dawn Part 2 trailer is out today, and the clip shows Kristen's Bella Swan after her vampire transformation is complete.
