Returning to the hotel room following the after-party, her now-fiance Travis Atreo popped the question.
"I almost dropped dead, it was so shocking. We had just finished the after-party and we were going back to change my shoes. I walk in and there were rose petals on the floor and I was very confused as to what was happening, and it just happened from there. It was so beautiful, exactly perfect.
"I'm still processing everything. You know, when you have the most extreme emotions of love, joy and happiness, it's almost too much to process."
When Maki was watching Toy Story as a kid, she certainly didn't expect to be part of its illustrious cast one day.
"Toy Story is probably the first movie I ever saw in the theatre, so that in itself is an experience I will never forget," Maki said. "It's a movie that really helped shape my childhood and so many parts of my identity and who I became in life."
So to be in a room with Tom Hanks, Tim Allen and all the people who have voiced these beloved characters for 24 years was madness.
"I met them after the film was completely done and we did this giant press day and everyone was getting together for the first. That was a crazy day. I had to keep pinching myself and saying, 'oh, you're actually in the film and not at some crazy Toy Story meet-and-greet'.
"They're all here in this one room and I get to tell them how awesome they are. To actually be a character within that is mind-blowing. Honestly, I thought I would probably have one line and that will be the coolest one line I'll ever have in my life."
Maki voices one of the many new characters in Toy Story 4, the pint-sized Giggles McDimples, a small police officer figurine with a larger-than-life personality.
Giggles is a great friend to Bo Peep, after Bo set off on her own adventure in the time between Toy Story 2 and Toy Story 4.
Together, Giggles and Bo make what Maki called a "phenomenal girl power duo".
"It's so inspirational to have that within the Toy Story universe. They're going to resonate so much, especially with younger girls of the next generation. We need to show more of how female friendship is so important, and that can be the element that changes your life."
Toy Story 4 is in cinemas now.
