After the wedding, the guests were taken to Granite Lodge, where they were treated to a locally produced dinner.

The actress then slipped into a floral embroidered tulle dress, while Michael wore a three-piece Brooks Brothers suit.

Rather than use traditional vows to commit to one another they penned their own romantic words, according to Martha Stewart Weddings - which helped organize the nuptials.

Kate and Michael asked their wedding planning team - which included Martha Stewart Weddings and The Ranch at Rock Creek's General Manager Maja Kilgore - to create a theme which was a combination of the English Victorian period and the American Old West.

The four-day celebration was snapped by photographer John Dolan and the wedding will be featured in the Winter issue of Martha Stewart Weddings.

The pair met when he directed Kate in the drama Big Sur in 2011 and the actress has admitted that it was love at first sight.

Talking to InStyle this year, Kate revealed: 'I never even dated my husband-to-be,'

Adding: 'He said to me after just a few weeks before we were even together, 'I'm going to marry you.' He just knew.'
