Chris Pratt announces his engagement to Arnold Schwarzenegger & Maria Shriver's daughter, Katherine Schwarzenegger

Before Chris Pratt could get down on one knee to propose to Katherine Schwarzenegger, he had to have a very important conversation with her parents.

The actor, who announced his engagement to Schwarzenegger on Sunday, spoke to her parents, Maria Shriver and Arnold Schwarzenegger, to ask for permission before popping the question, a source tells PEOPLE.
“He asked for Maria and Arnold ’s blessing and was very traditional about things,” says the source. The source adds the question came as no surprise to her parents — Pratt, 39, has long been vocal about his desire to start a future with Schwarzenegger, 29. “Chris has been very straightforward about his intentions from the beginning,” says the source.
“Over the last few months, he’s been bonding with all of Katherine’s siblings and it was clear to her entire family they would get married.”
