Chris Pratt and Katherine Schwarzenegger have officially tied the knot

Congratulations are definitely in order!

Chris Pratt and Katherine Schwarzenegger are now husband and wife, with the couple breaking the news that they had tied the knot over the weekend, in Montecito, California.

'Yesterday was the best day of our lives!' Chris posted to Instagram alongside a photo of the happy couple post-ceremony. 'We became husband and wife in front of God, our families and those we love. It was intimate, moving and emotional.'

He continued: '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 couple wanted to keep it simple, but have the most important people in their lives there,' a source told Entertainment Tonight, going on to add that Anna Faris, Chris' ex-wife was also in attendance.

Anna has been very supportive of the union, publicly voicing her excitement on Chris' engagement announcement.

‘Sweet Katherine, so happy you said yes!’, Chris announced of the engagement earlier this year alongside a photograph of Katherine. ‘I’m thrilled to be marrying you. Proud to live boldly in faith with you. Here we go!’

'I’m so happy for you both’, Anna commented, before throwing her hat in the ring for the role of minister.

There aren't many details on the wedding ceremony yet, but it is reported that there were numerous celebrities in attendance, including of course father of the bride Arnold Schwarzenegger who walked Katherine down the aisle.

Huge congratulations to Chris and Katherine!
