The Superman Returns actress said "I do" to Michael in Montana, US, at the beautiful Ranch at Rock Creek in a country-style wedding.
Last week Kate spoke about her upcoming wedding in an interview with Net-a-Porter's digital magazine The Edit.
Talking about the wedding dress, she said: "There was no doubt about the designer, [but] there was a feeling of, 'do I dance around the bridal thing and wear a dress I could wear for the red carpet?'
"But lately I'm all about coming out of my comfort zone and challenging myself, so I decided to embrace the moment. It has been a real discovery of that part of myself. I have never thought about it - the dress, the ring, any of it."
The 30-year-old actress met Michael, 42, on the set of the 2011 film Big Sur and he proposed to her a year later.
Kate revealed, in an interview with InStyle Magazine, that Michael planned to make her his wife even before the pair started dating.
"I never even dated my husband-to-be. He said to me after just a few weeks, before we were even together, 'I'm going to marry you.' He just knew."
Congrats to the happy couple!
