In second place is the less-surprising season six's Martha Kalifatidis, who boasts 333,848 followers and makes a comfortable living as an influencer.
The 31-year-old frequently serves up makeup tutorials and fashion inspiration to her followers and since she and her partner Michael Brunelli are one of only three MAFS couples who are still together, her boyfriend often pops up on her feed too.
However Daily Mail Australia discovered back in April 2019 that Martha may have purchased some of her followers with the publication reporting at the time that 103,700 of her followers are 'ghost pages' - ones that are not believed to be genuine accounts.
Taking the bronze medal for Instagram followers is another season five bride Sarah Jane Roza with 332,102 followers.
Like Martha, the curvaceous makeup artist who was married to Telv Williams on the show loves showing off her beauty and fashion looks but is also an advocate for health, particularly mental health.
"Always remember that whoever is trying to bring you down, is already below you," she wrote in a recent post.
"It’s taken me a long time to understand this life lesson & now after years of having a really solid grasp of what this message actually means & actioning it everyday, I want to impart this advice upon those who may be struggling... . If you need to hear this today then it’s definitely meant for you. Maybe you just need a reminder of how great you truly are... . Stay strong all you Queens & Kings."
Trailing behind the top three are former brides Lizzie Sobinoff, Jules Robinson and Cyrell Paule - all of whom starred on the 2019 season.
Meanwhile Davina's ex Ryan Gallagher is the groom with the most followers at 230,967. The lovable larrikin also starred on the 2020 season of I'm A Celeb which no doubt helped give him a push in terms on Instagram followers.
The big takeaway from this investigation is that Nasser was wrong - it is about hashtag Davina and hashtag coconut oil.
