The Australian model enjoyed the Balenciaga show at Paris Fashion Week in 2010 because she feels that she and her son Flynn - who was born in January 2011 - did the job together.
"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," femalefirst.co.uk quoted her as saying.
Kerr, married to actor Orlando Bloom, has taken a step back from modelling since giving birth. Although she features in apparel brand Bally's spring/summer 2012 campaign, she is trying to keep a healthy balance between her personal and professional life.
"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," she said.
"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.
