Kate Bosworth has shared a photo of her engagement ring with her Twitter.com followers and insists she feels "truly blessed" to be betrothed to director Michael Polish.

The actress let slip last month that she and Polish are preparing to wed by referring to the filmmaker as her fiancé in a travelogue blog for Vogue magazine.

Bosworth has now shown off her ring for the first time in a picture on her Twitter account and thanked fans for their well wishes about her upcoming nuptials.

In a post on Tuesday, she writes, "This photo was taken by my husband-to-be. Thank you all for the wonderful engagement wishes... We feel truly blessed."
