And pictures of the first moment he took the little one out in public for the day have now emerged.
The Celebrity Big Brother star couldn't wipe the smile from his face as the trio enjoyed a walk in the park.
And he looked every inch the doting dad on their adorable day out, tenderly holding the newborn as they stopped to catch their breath.
The new mum looked chic for the outing, opting for a black top and black jeans.
She covered up against the cold in a long cardigan, with fur detail.
The Irish model went for a casual look, in a pink t-shirt and jeans.
He completed the outfit with a black jacket, and beige Chelsea boots.
It seems the pair, who had a turbulent romance last year, are attempting to rebuild their relationship for the sake of their son.
It’s the first time the former couple have been seen together in public since Jeremy revealed he was the father of the 23 year old’s baby.
The tattooed hunk – who revealed he was feeling blessed recently – confirmed the news on Instagram earlier this month, sharing a snap of the one-month-old on his account.
