Miranda Kerr's most "special" career moment was taking to the catwalk when she was pregnant.

The Australian model enjoyed the Balenciaga show at Paris fashion week in September 2010

because she feels that she and her son Flynn - who was born in January 2011 - did the job "together".

She said: "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."

Miranda - who is married to actor Orlando Bloom - has taken a step back from modelling since giving birth, and although she stars in Bally's spring/summer 2012 campaign, she is trying to keep a healthy balance between working and being a mother.

She added to Vogue.co.uk: "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."

"It's working out well at the moment because I'm doing fun jobs here and there and getting to spend lots of time with my boys."
