'Guardians of the Galaxy' star Chris Pratt has tied the knot with Katherine Schwarzenegger, the daughter of Hollywood actor and former Cali governor Arnold Schwarzenegger.

Schwarzenegger, 29, and Pratt, 39, announced the news via their Instagram pages.

"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," they wrote in their moving posts.

Here's the full quote:

"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."
