Hawn’s Instagram post for Russell’s birthday included a video from the 1989 Oscars ceremony, where Hawn and Russell presented the award for Best Director. The clip she shared is the bit they did before reading the nominees. (You can watch the full video here.)ae0fcc31ae342fd3a1346ebb1f342fcb “We fit in completely to the theme of the show,” Hawn said at the start of the clip. “Because we’re co-stars, we’re compadres, we’re companions, and we’re a couple.” (That year, presenters were paired up by having at least one of those four connections.) “Yeah, there’s only one thing we’re not,” Russell responded. “What?” asked Hawn. “Married,” he said. Hawn then giggled and asked, “Is that a proposal?” After the crowd got excited, Russell said, “You’re putting me on the spot. I guess now’s a good a time as any to answer that… Oh, they want us to speed things up, so we’ll talk about it later tonight, okay?” For more celebrity news delivered right to your inbox, sign up for our daily newsletter. Given that they’re been together for nearly 40 years, Russell and Hawn have been asked repeatedly about why they decided not to get married. The answer is pretty simple: They both were married before and it wasn’t for them. “We’ve been married before, didn’t work. So why do it again?” Hawn said on the U.K. talk show Loose Women in 2015. She explained that the financial side of things turned her off from the idea. “Marriage ends up being a business deal, because at the end of a marriage, no matter how long or short it is, somebody owes somebody money,” she said. “It’s ridiculous to base your relationship on money, and money can destroy people.” On the Today show in Nov. 2020, Russell said that after he and Hawn decided to live together, “we said if this is ever an issue, if the kids feel we need to do this, then we’ll get married.” But, Hawn added during the interview, “they didn’t want us to get married.” And for more famous families, check out 13 Celebrities You Had No Idea Were Related. In addition to the Oscars video, Hawn wrote in her Instagram post: “Happy birthday baby! What a wild ride. No, we never got married but one thing that continues to grow is our love.” She went on to praise her partner of 38 years, writing, “You’re a wild one, brilliant, lovable, childlike, perfectly maddening, a father supreme and deeply funny! I can’t imagine my life without you at any age, Kurt Russell. You’re the catch. And you’re all mine.” And for more long-lasting pairs, check out 20 Long-Term Celebrity Couples You Totally Forgot Are Still Together. When they got together in 1983, Hawn had two children, Kate and Oliver Hudson, from her marriage to Bill Hudson, and Russell had a son, Boston Russell, from his marriage to Season Hubley. Together, they welcomed another son, Wyatt Russell. Kate considers Russell her father, and she posted a lengthy message for his 70th birthday on Instagram. After pointing out that he’ll probably never see the post since he’s not on the platform, she explained the kind of dad he is: “Don’t cry, shake it off you’re ok, kinda dad. Don’t let ’em push you around you got this, kinda dad. Don’t listen to the noise you’re doing great, kinda dad.” The actor continued, “He’s an original. One of kind. A powerful, intelligent, talented, loyal family man. He has taught me that we can all exist with immense love through our differences. And his dedication to my mother and their fight for love forever is as admirable as it gets. I love this man so much!” And for more on her family, check out Kate Hudson Posts Rare Photo of All of Her Kids Together.
