Lou also shared an image celebrating her pregnancy, she wrote that she was going to share a long post about their year "because ohhhh my life it's been a year all right" but said they'll start with how they are finishing - and ended it with a baby emoji.
Walker (Ngai Te Rangi, Ngāti Pūkenga, Tūhoe, Ngāti Porou, Tuhourangi, Ngāti Wāhiao, Ngāti Pikiao) this year told the Herald his "biggest flex" is his little family, Lou and her son Te Puuwairua.
"Before being a singer, I dreamed of being a dad and a husband," he told the Herald.
"I didn't think I was worthy enough to be that growing up, and then far out, I got everything I ever wanted. It's pretty mean."
The singer, who proposed to his now wife Lou last December, is a stepdad to little Te Puuwairua, and he couldn't be prouder of his little whānau.
"It's the most rewarding thing and the best thing I've ever achieved in my life, to inherit this beautiful boy. That's my son, that's my boy, he will always be the first of everything that I have. When we have more kids, he's the first. That's how we are as Māori. There's no step, half - that's my boy.
And he said then Lou was "just the most incredible mum".
