The 38-year-old model made the announcement on Monday afternoon sharing a picture of her ultrasound announcing she and boyfriend Shaun Hampton were expecting a baby.
“I’m so excited and thrilled to announce that my boyfriend Shaun and I are expecting our first child together and I’m 13 weeks pregnant,” she wrote.
“We have prayed for this beautiful little soul to come along and now it’s happened we could not be more thankful and we can’t wait to be parents.
“SO looking forward to meeting you our little angel.”
Hampson, 25, plays AFL for Richmond and has been with Gale since 2010.
Gale revealed her desire for children in an interview with The Weekly last year, saying her age didn’t concern her.
“I would love to be a mum one day – and it’s probably again going to be one of those things that is better late than never, considering I’m 37,” she said.
“And I do get too worried about the age factor either because I think women of my generation are having children a lot later. It’s definitely riskier and there are issues, but I think women are really wanting to get a lot of life experience under their belt – whether that be travel or work – and are becoming more certain about who they settle down with.”
Megan’s relationship with Hampson initially attracted attention because of the couple’s age difference – he is 13 years her junior.
“I know there are people who raise their eyebrows at the age difference. But if he was 13 years older than me, no one would mention it,” she told The Weekly.
“He is far and away more mature than guys I have gone out with who are five and six years older than me. So it doesn’t really matter. He’s focused and mature beyond his years.”
