The Wonderland star slyly announced on a recent blog post that she is engaged to her director beau, Michael Polish, after recently returning from a trip to South Korea.

The 29-year-old shared:

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

Bosworth and Polish met on the set of Big Sur, which hits theaters later this year, and they made their official debut as a couple at a Coldplay concert in August 2011, after the actress ended her two-year relationship with True Blood star Alexander Skarsgard a month prior.

It was only a matter of time before Kate made the engagement announcement; we spotted them wearing matching rings way back in October.
