Hundreds of her 1.5 million followers flooded the comments section with their well wishes, including a few familiar Aussie faces.
“Awwwwwwww squeeeeee!!!! So stoked for you!!!!! 😍😍😍” penned Turia Pitt.
“Congratulations guys!!!!!” added fellow fitness guru Kayla Itsines.
The Bachelor stars Bella Varelis, Abbie Chatfield and Brittany Hockley also congratulated the pair, as did fellow mum-to-be Elyse Knowles, who announced her own pregnancy back in September.
“How exciting! Congrats guys,” she said.
The soon-to-be-dad shared a similar snap to his own IG account, writing, “Our little family is getting a little bigger soon. We are so so excited to meet you little one!”
The couple were high school sweethearts and tied the knot in an intimate ceremony on their family property in country Victoria in November 2019. Their wedding was a year to the day that they got engaged - in exactly the same spot.
Steph wore a custom-made One Day Bridal two-piece for the ceremony – featuring a crop top and long, flowing skirt. Later, she switched to a silky slip with a cut out on the side and fittingly, opted for sneakers.
In the lead up to the big day, Steph opened up about her eating and exercise regime on social media.
“So many of you have messaged me asking what I’m doing in the lead up to the wedding and my answer is... nothing outside of the usual!" she shared. "I love working out, I love eating well, but I also love pizza, cheese, wine and chocolate and I haven’t deprived myself of any of those things leading up to the wedding. Why? Because when I’m too strict on myself I’m not happy, and I’d rather be happy in the lead up to the wedding."
Congratulations to the couple! We can't wait to meet this genetically blessed baby.
