Revealing that she and her partner Robert Sweeting were celebrating their first anniversary as husband and wife, Uzo quoted classic rom-com When Harry Met Sally.
"When you realize you want to spend the rest of your life with somebody, you want the rest of your life to start as soon as possible," she wrote, before calling Sweeting "the best thing" that had ever happened to her.
"For some of us, it can feel like we spend our whole lives waiting for our special someone. My heart, my love – I'm so happy my life started last year with you," the actress continued. "You're the best thing that ever happened to me."
Uzo isn't the only Orange Is the New Black star to be hearing wedding bells, as Taryn Manning, who played Tiffany 'Pennsatucky' Doggett, recently got engaged to her girlfriend Anne Cline.
Confirming reports that singer-songwriter Anne interrupted one of her own gigs in Florida to propose, Taryn told US media outlet TMZ: "It was the easiest YES I ever said!"
Elsewhere, in other OITNB-related news, Laura Prepon recently explained why she has taken a break from acting following the conclusion of the Netflix series, admitting that she hasn't yet found another role that lives up to her experience as Alex Vause.
"Orange Is the New Black was so incredible, to work with all of those incredible actors and direct multiple episodes, it's hard to find something that lives up to that," she said.
"Now, my first question is how long is it going to take me away from my family. Now that I have two kids, everything is a family decision."
