The model announced the birth of their son on Instagram on June 15 alongside a gallery of sweet photos.

‘Jaeger Justin Hemmes 1.06.25,’ she captioned the post, which has received over 3,000 likes since being posted.

This is the model’s first child with the billionaire Merivale owner.

He shares two daughters – Alexa, nine, and Saachi, seven – with his ex-partner Kate Fowler.

In November, an insider confirmed the exciting news of Madeline’s pregnancy to Daily Mail.

They revealed a friend of Justin’s had moved out of his Vaucluse mansion to make room for their growing family.

The business mogul, who has a net worth of $1.39 billion, began dating Madeline in 2019.

Justin and Madeline have gone from strength to strength since going public, and even sparked engagement rumours in June 2023.

Eagle-eyed fans noticed Madeline was wearing a ring on her wedding finger and questioned whether Justin had popped the question.

A photo captured her wearing the jewelry as she snuggled up to Justin while they savored a bowl of udon noodles at a high-end restaurant in Japan.

But the bling appeared to be an emerald and diamond promise ring.

Another photograph showed her wearing a different ring on the same finger as she posed for a selfie.
