On Tuesday, Golding, 35, and Liv, 37, attended the Los Angeles premiere of Avatar: The Way of Water at the Dolby Theatre.
The Persuasion actor wore an all-black ensemble, while yoga instructor Liv wore an orange-and-red sequined dress, accessorizing her look with open-toed black heels and a matching handbag.
After spotting each other from across the room, Liv decided to make the first move. "She steps in my way and she's like, 'Why haven't you said hello to me yet? I'm leaving tomorrow and you're never going to see me again. What are you going to do about it?' " he recalled during a 2019 appearance on Live With Kelly and Ryan.

"There's always a little bit of magic when you first meet a person, but it doesn't occur to you," Golding previously told PEOPLE about meeting Liv. "It's not like, 'Oh my God, that's a person I'm going to marry.' "

"There's like, 'Wow, there's something about them,' but it's when you get to know somebody, when you build a relationship, that you become a team. That's when you start realizing, this is the love of my life," he said.
Golding added at the time that he thought Liv, the founder of online fitness studio Fitsphere, which offers yoga classes with High-Intensity Interval Training or weights, "wishes that I've worked out with her more."
"And I wish that I worked out more with her because she's an amazing yogi," he said, noting that he wished he were "a lot more flexible than I am" while he filmed the 2021 movie Snake Eyes in Vancouver. "So I think I will pay more attention to her nagging me about getting in shape."
Avatar: The Way of Water is in theaters Friday.
