"Happy Father’s Day to my wonderful husband. Watching you be such a hands on and loving father was one of the many reasons I fell in love with you, and continue to each day," Katherine, 29, captioned a photo of the "Guardians of the Galaxy" star with his six-year-old son Jack. "I love you."
Pratt, 39, shares Jack with ex-wife Anna Faris.
In May, Schwarzenegger told Fox News her relationship with Pratt "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 also paid tribute to her own famous father, Arnold Schwarzenegger.
"Happy Father’s Day daddy! I love you so much." she wrote, "(even when you feed Maverick from the table)!"
