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 Katherine to wear and for me, the perfect suit. This morning we feel nothing but blessed.

The "Guardians of the Galaxy" actor announced the nuptials in an Instagram post on Sunday with a photo of the couple hand in hand.

They got married Saturday in a ceremony that was "intimate, moving and emotional."

Schwarzenegger is the daughter of actor and former California governor Arnold Schwarzenegger and journalist Maria Shriver.

The pair began dating last summer.
