Looking like she was walking a runway, wearing a super short black dress, Bosworth wore a super short black dress during her stroll with Polish, 41, and modeled her ring for the cameras. The director had a smile on his face as he held his fiancee's hand.

Bosworth and Polish made their debut as a couple at a Coldplay concert in August 2011 after meeting on the set of Big Sur (due out later this year).
