Kate Bosworth and Michael Polish wrote their own vows for their wedding.

The couple tied the knot on Saturday (31.08.13) at The Ranch at Rock Creek in Philipsburg, Montana, and rather than use traditional vows to commit to one another they penned their own romantic words to each other, according to Martha Stewart Weddings - which helped organise the nuptials.

Filmmaker Michael's 15-year-old daughter, Jasper Polish, was also part of the ceremony which took place overlooking beautiful hill-tops, glistening streams and mountains.

Kate, 30, wore a beautiful Oscar De La Renta strapless ivory ball gown - featuring an eight foot long, 16 foot wide train - teamed with ivory-coloured Jimmy Choo sling back heels, which were encrusted with crystals across the front strap for the nuptials.

Later on the 'Straw Dogs' star changed into a floral print tulle dress with scalloped cap sleeves for the reception.

Michael, 42, donned a three-piece charcoal suit from Brooks Brothers.

Following the ceremony, the newlyweds and their guests - who included actress Lake Bell, Oscar-winning actor-and-producer Walton Goggins and Michael's twin brother Mark Polish - made their way to the Granite Lodge for the wedding breakfast and speeches before everyone moved into the Silver Dollar Saloon for music and dancing and cocktails.

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.
