Kate Bosworth and Michael Polish Posing in Sydney

Kate Bosworth posed alongside fiancé Michael Polish in Sydney last night. She wore a sequined Stella McCartney dress for the occasion, which celebrated the launch of the SK-II skin care line at retailer David Jones. Kate was named a new face of the luxury company last month, joining longtime ambassador Cate Blanchett, and has since participated in three photo shoots for the brand. Kate and Michael arrived in Australia earlier this week and have been exploring Down Under. They were arm in arm for a sunny stroll on Tuesday and checked out Bondi Beach yesterday.
