Overjoyed fans were quick to take to social media to congratulate the couple on finally taking the plunge and making their relationship offical.
“OMG! Did you get married? You look gorgeous and Steve so handsome. Congratulations,” One fan wrote.
“So happy for you guys and your little man,” another person wrote.
A third person added: “Wow, congratulations Mish and Steve. Great news.”
While the black and white snap at first glance looks exactly like a traditional wedding pic, the fitness guru’s follow-up message seemingly shut down any wedding talk.
‘A flash back to the Logies a few years ago,’ Michelle captioned, referring to her outfit from the awards ceremony two years ago.
Michelle’s cryptic post come after she previously spoke candidly about taking time away from Steve and bub, Axel, during filming for Dancing with the Stars.
In February, the fitness queen took to Instagram to address her heartache at being away from the family nest, while training for the dancing show.
"A new appreciation to all the mums out there … who have to make that decision which results in being away from your bubbas and family,” she wrote at the time.
