Chris was previously married to actress Anna Faris for eight years before they split in 2017. They share a son together, five-year-old Jack, and have candidly spoken about co-parenting since their divorce.
During an episode of her podcast, Unqualified, Anna said: "Chris and I work really hard ‘cause we have Jack, that is sort of the long game idea and making sure Jack is really happy, which makes us really happy.
"We have sort of the luxury of circumstance. You know, we are both in other loving relationships…But It’s like, how do you not in general sink into a place of bitterness?"
Faris also commented on Chris' Instagram announcement, writing: "I'm so happy for you both."
Chris recently told E! Entertainment: "Divorce sucks. But at the end of the day, we’ve got a great kid who’s got two parents who love him very much.
"And we’re finding a way to navigate this while still remaining friends and still being kind to one another. It’s not ideal, but yeah, I think both of us are actually probably doing better."
Congratulations to Chris and Katherine!
