(CBS News) Kate Bosworth says she and director Michael Polish are engaged.

The "Straw Dogs" star casually mentioned the couple's relationship status in a travel blog she wrote for Vogue.com, in which she referred to Polish as her fiance.

"On our first day in Seoul, my fiance, Michael Polish, and I venture out to discover Changdeokgung Palace," Bosworth wrote.

The actress, 29, stars in the upcoming film "Big Sur," which was directed by Polish, 41. The two were first spotted together at a Coldplay concert last August, according to People.

Bosworth previously dated "True Blood" star Alexander Skarsgard.
