The 34-year-old took to Instagram to announce the exciting news, writing, "WE’RE HAVING A BABY! In what’s been a crazy 2020, we see a little baby light at the end of the tunnel. We’re over the moon, and can’t wait to meet our little Biscuit."
The couple posed next to a sonogram of their bub, revealing the podcast host is at the 13-week mark.
Neil shared his own post writing, "We’ve been busy in iso baking a 'Biscuit'!"
In his post, he shared a video of Carly after getting an ultrasound with the former reality star telling the camera, "I have an announcement to make you guys, there's something in here," as she pointed to her stomach.
The pair moved in together earlier this year as the coronavirus pandemic struck Australia, forcing us into lockdown.
Speaking to The Daily Telegraph after they'd moved in she said it was "a learning curve".
"On one hand, it's great to have a partner there for support in a really uncertain time and I'm so thankful to have Neil around," she said.
"But he's also the only person that I've seen for the past few weeks, so of course with that comes its own raft of issues!"
She continued, "Most people aren't used to spending so much time with their partner... living, eating, working, exercising, sleeping and there's nowhere else to go."
In April, Carly shared a birthday message for Neil, calling him her "favourite person".
"You’re equal parts hilarious, annoying, and full of life, and I wouldn’t have you any other way. Love you," she wrote.
The pair appear to have been dating for almost a year with Carly sharing her first photo of them together last August.
Congratulations to the happy couple!
