The gorgeous photos, shared on Jasmine's Instagram, showcased a completely decked out pink table, an array of pink and white balloons, stunning pink flowers, and laughing family and friends.
"1st Birthday Snapshots 📷" Jasmine captioned the post. "Thank you @laraincevents what an incredible 1st Birthday for our baby girl we couldn’t have done it without you. 💗 and @janetfitz53 that cake was incredible! 🤍🙏"
Among the images were shots of the party's attendees, including the entire Stefanovic clan. Standing out from the pack was Karl's mum Jenny and brother Peter who donned a matching black and white tracksuit with his first son Oscar.
Also featured was a photo of Oscar with his cousin, not to mention the birthday girl, Harper sitting face-to-face. So cute!
While there was some speculation that Karl was not in attendance for the big day, a photo within the series proves he was well and truly there to celebrate the important milestone.
The proud father held his daughter up as she stood on a table while loving mum Jasmine looked on and clapped.
Karl and Jasmine welcomed Harper on May 2nd, 2020.
Jasmine is also the step-mum to Karl's other children, Jackson, 22, Ava, 16, and River, 14.
And, rumour has it, the couple have another baby on the way.
