Fans couldn't believe the results Johnny attained in such a short space of time.
"Only 30 days 😮. Dang. Great results," one remarked.
But the most glowing review came from Kerry Knight, Johnny's MAFS-bride-turned-official-girlfriend.
"🔥🙌🔥🙌🔥🙌 (in all three photos! 😉) I’m a lucky girl x," she gushed.
Johnny and Kerry may have entered the experiment as intruders but they quickly became one of the season's most beloved couples.
Along with Bryce Ruthven and Melissa Rawson, they are one of two couples from season eight still together in real life.
To mark a year since their MAFS experience, Kerry shared a reel to Instagram of some of their behind-the-scenes highlights.
"Almost a year on, here’s a ‘reel-y’ quick glimpse of some candid pics from our first few weeks together ❤️@johnnybalbuziente … love you x," the former TV bride penned in her caption.
Since their time on MAFS, Johnny and Kerry have moved in together in Brisbane and welcomed puppy Enzo to the family.
Johnny surprised his girlfriend with the pup to celebrate her recent 31st birthday.
"Welcome to our family ENZO. Officially. The. BEST. Day. Ever," she captioned a video of Johnny sitting with Enzo.
