Congratulations are in order for actress Kate Bosworth, who wed her director boyfriend Michael Polish this weekend.

The pair met when they worked together on the 2011 film 'Big Sur,' and she says it was love at first sight.

"I never even dated my husband-to-be," Bosworth told the September issue of InStyle UK (quotes via PEOPLE). "He said to me after just a few weeks before we were even together, 'I'm going to marry you.' He just knew."

Turns out Michael was prescient, because Martha Stewart Weddings reports Kate, 30, and 42-year-old Michael swapped vows they wrote themselves when they wed on Saturday at the rustic Ranch at Rock Creek in Philipsburg, Mont.

The 'Superman Returns' actress wore two custom dresses by Oscar de la Renta during the festivities: Her wedding gown was an ivory satin strapless dress with a sweeping train, and for the reception, she changed into a floral embroidered tulle frock with cap sleeves and an illusion neckline.

It's Bosworth's first marriage and Polish's second (he and make-up artist Jo Strettell divorced in 2004). Our best wishes to the newlyweds.
