Chris Pratt admitted to feeling some nerves before asking for Terminator actor Arnold Schwarzenegger's blessing to propose to Katherine

Even Galaxy-saver and Marvel superhero Chris Pratt was a little intimidated before facing his hopeful father-in-law.

The 39-year-old actor admitted to feeling some nerves before asking for Arnold Schwarzenegger‘s blessing to propose to his oldest child, 29-year-old daughter Katherine.

Well, I think any person who appreciates the tradition and asks a father for his daughter’s hand in marriage, it’s inevitably something that’s going to make you a little nervous,” Pratt recently told Extra. “But that’s sort of the beauty of it.”

But it turns out Pratt didn’t have much reason to be nervous. A few weeks after Pratt popped the question, the Terminator actor, 71, sat down for an interview on Extra with Mario Lopez where he revealed his thoughts on his future son-in-law for the very first time.

“That was really fantastic. She is so happy, they both are so happy,” Arnold said of the couple’s engagement. “As I said to him, he is such a likable guy. I love Chris — he’s fantastic.”

The former bodybuilder went on to reveal that Pratt asked for his blessing in the “traditional way” before proposing to Katherine.

“He’s a wonderful guy,” Arnold added. “They both look really great together, they’re both happy together, so I wish them both the best of luck.”

Pratt also told reporters at the Lego Movie 2 premiere that he and Katherine hadn’t “really” figured out too many wedding details yet.

Sharing a hint about their possible wedding date, he mentioned they were “maybe” thinking of a “fall, winter kind of thing,” before adding that they still have “a lot to get done.”
