The news comes days after Pratt fuelled rumours through social media that they are moving in together.
Just a day prior, USA news media reported that Chris helped Katherine move out of her Santa Monica, California home.
Chris Pratt announced on Monday, January 14, that he is now engaged to Katherine Schwarzenegger. She authored the children's book Maverick and Me in 2017 and the positive self-image book Rock What You've Got: Secrets to Loving Your Inner and Outer Beauty from Someone Who's Been There and Back in 2010.
Pratt, 39, revealed on Instagram that Schwarzenegger, the 29-year-old daughter of Arnold Schwarzenegger, accepted his proposal. Proud to live boldly in faith with you. The former couple share one son, 6-year-old Jack. "Thankful for the laughs, kisses, talks, hikes, love, and care." . This was Pratt's first Father's Day since his divorce from Anna Faris.
