A number of celebs took to the comment section to share their well-wishes.
Rebecca Maddern wrote: "Congratulations. Enjoy the love bubble and the wonderful time as a family."
Zoe Foster Blake added: "Welcome, Frankie! Congrats, mum and dad! You just happy-ed up everyone’s feed by a zillion percent!"
Fashion designer Toni Maticevski sent dozens of love heart emojis, while Jules Sebastian wrote: "Congrats you guys! She’s a beauty! X"
The gorgeous pair welcomed Frankie a year after suffering from a heartbreaking miscarriage.
“Last year was such a tough year for Jake and me. It was the toughest year of our lives. I felt like I almost broke and, in fact, it’s still really raw,” she told Stellar magazine in August.
“But Jake was amazing. He let me sit with the pain, feel it and not be OK.”
The 35-year-old went on to say that 'everything crumbled' when they discovered the baby had no heartbeat at the first scan.
But on the 10th of May, the Australian model made an announcement via social media that she was expecting her first child.
Taking to Instagram Jen wrote: “I’m sooo happy to share with you some exciting news! Jake and I are expecting a baby girl!!! We can’t wait to meet her!
“Thank you to our beautiful family and friends for their love and support and, most importantly, to my hubby Jake — I can’t wait to see you as a Daddy! @jakewwall xx”
