Since his little man's arrival back in September, JB hadn't shared any photos of his child.
But after spending some time away from home, the dad-of-one couldn't resist sharing one very cute snap with us all.
Currently in Austria training for Channel 4's The Jump, JB has been forced to spend time away from his missus and their baby boy.
Finding it hard being away from his family, the doting dad took to Instagram yesterday (18 January), telling fans he was "missing his two loves".
In his photo, Chloe can be seen cradling the couple's son Ace, while he stares into the camera all wrapped up in his hood.
Just look at those big eyes and his cheeks! He's such a cutie, right?!
On seeing his post, many of JB's followers complimented the former boyband star on his beautiful baby.
One user said: "Wow JB he is gorgeous!!!" While another commented: "Lovely picture so cute."
JB and Chloe welcomed Ace - their first child together - on 19 September last year.
Shortly after his birth, the X Factor star announced the arrival of his son on Twitter. He tweeted: "A little nose, lots of hair and looking like his mummy, our baby boy was born 19/09/14 weighing 6lbs 15oz."
JB's wife Chloe announced her pregnancy just three months before Ace's birth back in June.
Their baby joy came just one month after the couple - who have been together for six years - tied the knot in front of their family and friends.
Meanwhile, JB has been busy conquering the slopes while preparing for this year's series of The Jump.
Taking on the winter sports competition, he will be joined by the likes of Joey Essex, Ashely Roberts, Stacey Solomon, Louie Spence and Made In Chelsea star Louise Thompson.
Strictly dancer Ola Jordan was forced to pull out of the show early due to injury and has since been replaced by Dancing On Ice star Chloe Madeley.
