The 28-year-old Australian model said she enjoyed the Balenciaga show at Paris fashion week because she feels that she and Flynn did the job "together", reported Femalefirst.
"I was pregnant at the time, so my son Flynn and I walked the catwalk together. He was in my belly, so it made it really special," she said.
Kerr, who is married to actor Orlando Bloom, said she is trying to keep a healthy balance between working and being a mother.
"At the moment I'm trying to do 60/40 - I spend most of my time at home being a mother and only work on jobs that I really love and with brands that I really want to work with.
"I've cut back quite a bit because especially the travelling can be too much and my son is obviously my number one priority," she added.
