This is Gale's second child with AFL player partner Shaun Hampson.
In January the Australia's Next Top Model host revealed she had suffered a miscarriage in May 2015.
“There have been plenty of times in my life I’ve had to suck things up — but this was the most challenging time I’ve had to do that," she told InStyle Australia.
“I came home from having a procedure, hugged my boy for a few hours and had to pack a bag and go. Not being around loved ones was really hard.”
Gale is mum to two-year-old son River.
