Miranda Kerr has shared some parenting advice with her workmates after the announcement that a third Victoria's Secret model is pregnant.

The Gunnedah-born mum of Flynn, one, discussed babies with fellow model Erin Heatherton during a Victoria's Secret live-stream chat.

Victoria's Secret models Alessandro Ambrosia, Adriana Lima and Lily Aldridge are all expecting.

"I wasn't even sure if I wanted to come back to work or not when I had my son," Kerr said. "And now, you know, I work so much less than before I was pregnant. That's the choice I made."

"Flynn is my priority - being there for him, making sure that I can cook for him, spend time with him, is more important than anything else."

Flynn is my priority ... [he's] more important than anything else

Heatherton joked about the rash of pregnancies. "Is it in the water? Because I need to buy my own water," she said.

"I don't know what is going on ... They're dropping like flies. Who am I going to hang out with now?"

It's been a busy few weeks for Kerr - this week, she appeared on the cover of Who magazine's 'Most Beautiful People 2012' issue with son Flynn.
