Many of the couple's friends flooded the comments with congratulatory messages, including Anna Heinrich, Steph Claire Smith, Ash Barty and Bec Judd.
The 29-year-old model gave birth to Sunny Barker in February 2021, revealing to WHO that motherhood was “the best.”
"I'm adoring it!” She explained. “I feel like I say this all the time, but things get better and better every day."
“It’s been new, unpredictable, wholesome. I am loving the role of Mum, and grateful to be where I am with my beautiful family,” Elyse told WHO, shortly after her son’s birth.
"Sunny is growing into such a little dude now. He's so alert and fun, he's loving, full of smiles and he is so cuddly. I could smooch him all day long.”
“Josh and I often look at photos of him in bed. Almost every night the two of us look at each other thinking, "should we get him up for a quick cuddle?" It's tempting!"
While Elyse has worked as a model for years, fronting campaigns for brands including Seafolly and later signing on as Myer ambassador in 2018, she became a household name following her successful stint on The Block in 2017 alongside Josh.
The couple won the series after the house they renovated sold at auction for a whopping $3.067 million. The property was bought by Aussie comedian Dave Hughes.
The huge financial win allowed Elyse and Josh to pay off their own mortgage, with the couple making the move to Byron Bay to raise their family.
