U.S. actress Kate Bosworth said in a travel diary for Vogue.com she is engaged to director Michael Polish. The couple began dating a little more than a year when they collaborated on the soon-to-be-released film \"Big Sur.\" \"On our first day in Seoul, my fiance... and I venture out to discover Changdeokgung Palace,\" Bosworth said in a Vogue.com blog post Wednesday. E! News said the actress\' publicist did not immediately respond to a request for comment about her casual reference to Polish as her fiance in the blog post. She did not mention on Vogue.com when she got engaged or if they have set a wedding date.
