Kurt Russell and Goldie Hawn [1]'s incredible, three-decades-long romance [2] is the stuff of Hollywood legend, and no one is more amazed by their relationship than daughter Kate Hudson [3]. In honor of their recent 34th anniversary, the Deepwater Horizon actress shared a gloriously vintage throwback photo of her mom and Kurt, whom she affectionately calls "Pa," on Instagram [4]. "My #tbt is these two love 🐦's!" she captioned the black-and-white shot. "Mama Goldie and Pa killing it 80's style. I forgot to post a note on my parents 34th Anniversary so I figure why not now. A belated happy one my dear parents. Love you madly, deeply, profoundly ❤#HairGoals #Love @officialgoldiehawn." As if we needed any more proof, this photo only further confirms that the happy couple [5] and proud grandparents [6] are aging like fine wine.
