To celebrate Katherine's 29th birthday on Thursday, the actor shared a collage of photos to Instagram, writing: “Happy Birthday Chief! Your smile lights up the room. I’ve cherished our time together.”
He continued: “Thrilled God put you in my life. Thankful for the laughs, kisses, talks, hikes, love and care."
Katherine, Arnold Schwarzenegger and Maria Shriver's oldest daughter, responded by commenting: "😩😩😩 I love you ❤️❤️❤️"
Chris met Katherine at church in June through her mother. It wasn't long before the pair was spotted on dates and, according to E! News, are now considering moving in together.
Chris’ ex-wife Anna Faris is reportedly fine with Pratt's new relationship as Katherine "adores" Faris and Pratt’s 6-year-old son Jack.
"Luckily they [Pratt and Faris] are both dating people who love Jack and are very good with kids," a source told E!.
It looks like Katherine has the Pratt family tick of approval too with Chris' brother posting multiple photos of the new couple to Instagram.
