‘Our boy!!!’ she captioned the family photo, while revealing that he was born on June 4 at precisely 10:38pm and weighed 8.8lbs.
Max shared his own photo of himself holding their baby boy in a car seat with Binky beside him. ‘Home time with my champions. Proud,’ he wrote.
Leading the stream of congratulations, Girls Aloud star Kimberley Walsh wrote: ‘Congratulations! Enjoy your baby bubble sending so much love.’
Former Geordie Shore star Vicky Pattison commented: ‘Congratulations beautiful girl.’
Fellow MIC star Ashley James said: ‘Congratulations lovely❤️.’
Towie star Billie Faiers weighed in: ‘Congratulations to you all 🥰❤️ lots of love xxxxx.’
Binky, real name Alexandra Felstead, announced she was pregnant in December more than a year after she began dating Max.
She posted a photo of her daughter India holding up photos of the baby scan, and wrote in the caption: ‘BIG SISTER ALERT!!!
‘We are so thankful and excited that our family will be growing in 2021! India gets her new title of “Big Sister”… which she’s already very proud of!
‘2020 has been a real personal rollercoaster with some huge ups and some lows. We are so excited, happy and thankful for what is to come! Here’s to 2021 #babyincoming #no2.’
A week later, the reality star shared the baby’s sex in a reveal that hilariously went slightly awry as both India and Binky struggled to pop the balloon.
In the video, soundtracked by Somewhere Over The Rainbow, Max carried India as she tried to pop the large black balloon which had ‘boy or girl?’ scrawled on one side.
After several unsuccessful tries, Binky attempted to pop it with the pin herself but still to no avail.
A family member off-camera then handed over a large carving knife which, of course, did the job and spilled tiny pieces of blue confetti all over the floor, confirming that the happy couple were expecting a baby boy.
Binky and Max moved in together last year and he popped the question in September, with the couple sharing the news of their engagement on social media.
It’s the couple’s first child together as Binky shares daughter India with ex Josh ‘JP’ Patterson.
