Tammy Hembrow and her Ironman fiancé, Matt Poole have welcomed a baby girl.

Announcing the little one’s arrival to her 15.1 million Instagram followers on Sunday, Tammy wrote: “The absolute hardest yet most rewarding thing I’ve ever done. An unmedicated VBA2C. No words. Birth story to come. For now just resting in my love bubble with my perfect little girl.”

Tammy has not yet confirmed her daughter’s name.

Tammy shared this image a couple of days before meeting her baby girl.

The fitness influencer said the birth of the the baby girl was her “hardest yet”, but also the most rewarding. Tammy daughter arrived via a vaginal birth, after the previous two children were born by caesarean.

Alongside the baby news announcement, Tammy shared a carousel of images showing her incredible labour.

During her unmedicated labour, Tammy hoped a shower would provide some pain relief.

Tammy’s daughter is almost ready to make her long-awaited entrance into the world.

And she has arrived! Congratulations to Tammy and her fiancé, Matt Poole.

The Gold Coast fitness model also shares two children with her ex-fiancé Reece Hawkins – son Wolf, six, and daughter Saskia, five.

Tammy’s new baby girl was born with a rare genetic mutation, which is called Polydactyly, just like Tammy! You can read more on that below, but basically it means that she was born with 12 fingers.

The 27yo beauty, her sisters, mother and brother also had the mutation.

The extra fingers are usually small and abnormally developed and are removed via surgery at birth.

Surprise! 12 fingers.

Earlier this year, Tammy opened up with fans about her plans for a natural birth following two c-sections.

“Not going to lie it makes me a little nervous to be on this journey again,” she wrote alongside a series of images of herself cradling her bump while sitting on a bed.

“My births with Wolf & Sass definitely didn’t go how I planned or would have liked. Emergency c -section with Wolf & then another c-section with Sass after not even being able to trial labour due to risk of rupture.

“I’m so so excited to be trying for a natural birth once again but this time I have more faith in my body than ever. With my midwife, my hypnobirthing coach, & after witnessing the most beautiful natural births with my sisters I feel like I got this. My body was made for this, I am more than capable. I am so excited to try for VBA2C !! I have faith that everything will work out in my favour. & If it doesn’t, as long as I have a healthy happy baby I know I’ll be just fine🤍”

Tammy and Matt, a restaurateur and former ironman, have been together since 2020.

Earlier this year, Tammy also shared that during a routine ultrasound she found out that her baby girl has 12 fingers – a genetic condition she also had at birth.

In a video posted to YouTube, Tammy shared the suprise news with fans, that her unborn daughter has a rare gentetic mutation, which is called Polydactyly.

“We just saw the little baby, and the surprise was that she has 12 fingers, like me, like her mummy,” Tammy says in the video.

Tammy goes onto explain that her sisters, mother and brother also had the mutation.

Tammy says her daughter’s extra finger will be “cut off at birth”.

Tammy’s first two children, son Wolf, six, and daughter Saskia, five, who she shares with ex-fiancé Reece Hawkins, 26, did not.

“Amy and Emilee had extra fingers when they were born as well, and so did my little brother. So did my mum. It runs in my family,’ she explained.

“It skips a few people, like it skipped Wolf and Sass, but this baby has 12 fingers. Isn’t it crazy?”

In the YouTube video, which shows the ultrasound of her baby’s hand, Tammy says her daughter’s extra finger will be “cut off at birth”.
