The couple tied the knot at the San Ysidro Ranch in Montecito, California, on Saturday.
The couple took to Instagram at the same time on Sunday, just hours after they got married, to share the same photo from their wedding with identical captions.
In the photo, they are seen walking hand-in-hand while smlling at each other on their wedding day.
The caption on Katherine’s posts reads: “Yesterday was the best day of our lives! We became husband and wife in front of God, our families and those we love. It was intimate, moving and emotional. We feel so blessed to begin this new chapter of our lives.
“We are so thankful to our families and our friends who stood with us, and grateful to Mr Giorgio Armani, who created a once in a lifetime dress for me to wear, and for Chris, the perfect suit. This morning we feel nothing but blessed.”
Chris, who was married to Anna Faris for nine years before they divorced just last year, also shared the same caption with very minor modifications.
