Guardians Of The Galaxy star Chris Pratt has announced he has married Katherine Schwarzenegger in an "intimate, moving and emotional" ceremony.

The Hollywood A-lister made the announcement in an Instagram post with a picture of his new wife.

Author and lifestyle blogger Schwarzenegger, daughter of Terminator actor Arnold, also uploaded the picture to her own account.

The pair said it was the best day of our lives, adding they became husband and wife in front of God, our families and those we love.

They added: 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.

They also thanked Giorgio Armani who created a once in a lifetime dress for Schwarzenegger and a perfect suit for Pratt.

Schwarzenegger, 29, and Pratt, 39, said they feel nothing but blessed.

Pratt announced their engagement on Instagram in January, saying: Sweet Katherine, so happy you said yes! I’m thrilled to be marrying you. Proud to live boldly in faith with you. Here we go!
