Chris Pratt wrote a lengthy post on the photo-sharing app, along with a lovely couple photo.

The actor revealed he met Schwarzenegger “in church.”

He thanked her for giving him “an amazing life, a gorgeous healthy daughter.”

To show his appreciation, Pratt hilariously noted that he helps Schwarzenegger open "a jar of pickles” from time to time.

He also revealed that the tribute was for her upcoming birthday, which will take place in six weeks.

The new share earned over a million likes and thousands of comments from fans.

Actor Lewis Howes commented by stating, “That’s real love right here.”

In October, Pratt and Schwarzenegger took to Instagram and made an announcement about their involvement at the Special Olympics next year.

Pratt wrote in the caption: “Katherine and I are so humbled and honored to be joining Special Olympics as global ambassadors.”
