Posting an Instagram of their dog Harley with the same pair of shoes tied around his collar (bloody adorable), the mum-to-be echoed Smith’s sentiments.

“We’re having a baby! 12/2018,” she wrote, sharing their estimated due date.

“Bubby…. You are my world, my hero, my best friend, my soon to be baby daddy, my protector, my motivator, my light, my smile, my ONE. I can’t wait to meet our next member of this beautiful family we share.”

Smith first began dating the Instagram fitness influencer and trainer at Sydney’s popular Base Gym in 2017 after his breakup with model and nutritionist Maddy King in October 2016.

Speaking about his current girlfriend on his I’m A Celebrity…Get Me Out Of Here! appearance in 2017, it was clear he was smitten.

“She’s herself,” he said. “She’s such a good person and that’s why I was drawn to her.”

Australia’s Next Top Model fans might also recognise Boulazeris from her brief stint on seventh season in 2011.

Congratulations to the happy couple!
