Chris Pratt, 39, and Katherine Schwarzenegger, 29, tied the knot in a private ceremony on Saturday.
The Avengers star took to Instagram Sunday morning to thank all of the couple's loved ones for helping celebrate their union at the ultra-exclusive San Ysidro Ranch in Montecito, California.
'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,' Pratt wrote. '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.'
Katherine looked flawless in her strapless white wedding gown and simple veil as she smiles up at an equally-dapper Pratt outside their exclusive wedding venue, where the bride's Great Uncle John F Kennedy and wife Jackie spent their honeymoon in 1953.
The wedding took place at approximately 5.30pm local time, with Katherine arriving at the wedding marquee on the arm of her father, Terminator star Arnold Schwarzenegger.
Her Giorgio Armani gown featured a sweetheart neckline and long, lace-trimmed train. She accessorized with a pair of large diamond earrings, a simple bracelet and a bouquet of white roses.
Pratt's tuxedo by the same designer was accented with a simple silver tie and matching pocket square.
Her bridesmaids were dressed in floor-length blush pink gowns with plunging necklines.
