Kate Bosworth is engaged to Michael Polish.
The 'Blue Crush' actress revealed the information in a blog post about their recent trip to South Korea.
The 29-year-old star wrote: "On our first day in Seoul, my fiancé, Michael Polish, and I venture out to discover Changdeokgung Palace."
Kate and her director partner, who met on the set of 'Big Sur' - which is due out later this year - made their debut as an item at a Coldplay concert in August 2011 when they were spotted being affectionate with each other.
Prior to stepping out with Michael, Kate dated 'True Blood' actor Alexander Skarsgard for two years, before ending her relationship with him in July 2011.
Alexander is now dating an Italian skydiver.
However, while the screen hunk is happy to spend time with Roberta Mancino, 31, he is reportedly not looking for anything serious.
A source told Life & Style magazine: "He's been courting her and taking her out to dinner a lot. It's not a serious relationship, but they look forward to hanging out together even more. They really like each other."
