The "Avengers: Endgame" star told Extra on Tuesday at the opening of "Jurassic World: The Ride" at Universal Studios Hollywood, "We met at church! There's a lot of kismet … a lot of connections, but that is where we met."
He added, “Katherine is at home right now, and she and [Pratt's 6-year-old son] Jack are tie-dying shirts. Maybe they will make me one. I hope so!”
"It feels really nice. We just feel very blessed and very, very happy," he said, adding, "I think having the stress of the [wedding] ceremony behind you is kinda nice, you know? But, yeah, we're in the honeymoon phase. It feels really good and we just feel really happy."
Pratt and Schwarzenegger began dating in summer 2018 and married just a year later on June 8 at the San Ysidro Ranch in Montecito, California.
The two celebrated their honeymoon and Pratt's 40th birthday in Lanai, Hawaii.
The author previously told Fox News that her relationship with the "Avengers" star is “amazing."
“I think anyone who finds the person that they get to spend the rest of their life with… it’s a huge gift and a huge blessing, so I feel really lucky," she said.
Pratt's religion has come under fire in the past.
The "Guardians of the Galaxy" star's Hillsong Church has previously been criticized for allegedly being homophobic, a claim Pratt has vehemently denied.
