Just a few months after Chris Pratt and Katherine Schwarzenegger tied the knot, Arnold Schwarzenegger told Jimmy Kimmel, "I'm really happy that he is such a great guy. Not only a very talented guy and a great actor and a great star and all this stuff, but a really kind man and kind to my daughter, which is the most important thing for me." The kindness Schwarzenegger saw in Pratt is surely even more important now, as both have transitioned into new roles as a grandfather and father, respectively.

Pratt and his wife welcomed a baby girl named Lyla in August 2020, and Schwarzenegger told People that he's proud of the new parents. "They're doing really great together as parents" he said, while admitting that having a grandchild makes him feel old. While Pratt and his father-in-law are serious about being there for baby Lyla, they still manage to get a laugh in together every now and then.
