"Nawww.. congratulations ❤️❤️❤️," fellow model Megan Gale wrote.
"Yah!!! 2021 is quite the year for the Knowles Barker clan 💗," former E! News host Ksenja Lukich commented.
"The best!!! Congratulations love birds xx," Rebecca Harding shared.
In an interview with Stellar magazine earlier this month Elyse revealed marriage was far from her mind.
"I'm not really fussed about [a wedding]. The baby is the biggest commitment we need," she told the publication.
"We don't even think about that anymore. I'm not worried about it. I would rather put that money into family and our life all together. We know we love each other."
The news comes just months after the couple announced they're expecting their first child together.
Josh and Elyse, who have been together for eight years, revealed the news via Instagram with a series of snaps from a stunning outback photoshoot showing off the 27-year-old's baby bump.
"And then there were 3 #babybarker," Elyse captioned her post.
Elyse and Josh won The Block in 2017 after the house they renovated sold at auction for a whopping $3.067 million and was famously purchased by Aussie comedian Dave Hughes.
Following their reality stint, the couple embarked on a sabbatical to Byron Bay and have started a building and design business together, J&E Projects.
Elyse has worked as a model for years, appearing in campaigns for brands such as Seafolly, before she became a Myer ambassador in 2018 following her time on The Block.
