But one of those hundreds of commenters was none other than KIIS FM radio host and The Masked Singer celebrity panellist Jackie O, who posted several fire emojis on Martha’s photo.
Turns out the 30-year-old former makeup artist is a huge fan of Jackie O - and completely lost it once she realised the 45-year-old entertainment industry veteran had commented on her post.
Martha's boyfriend Michael Brunelli shared a candid video of her reading the comment in bed, with the caption, “When @jackieo_official comments on your photo.”
The influencer re-shared the clip to her own Instagram stories, explaining she is “low key obsessed with Jackie O”.
Martha has previously met Jackie IRL, when she acted as a co-host on Kyle and Jackie O's breakfast show last month.
Martha and Michael are one of the only successful love stories to come out of the Married At First Sight series, along with season two's Erin Bateman and Bryce Mohr and their season six co-stars, Jules Robinson and Cam Merchant.
The pair have both carved out lucrative post-show careers for themselves, with Martha earning a living from paid beauty, fashion and lifestyle endorsements on social media and Michael via his online fitness business, TrutFit.
