Naturally, the 49-year-old mum-of-one’s fans went wild over speculation the pair had tied the knot.
"OMG! Did you get married? You look gorgeous and Steve so handsome. Congratulations❤," one person wrote. "Beautiful. All those years ago who would’ve thunk it?! So happy for you guys and your little man ❤️," one of Michelle's friends wrote, to which she replied "Thanks tarsy 😍😍😍," seemingly confirming the news.
However, eagle-eyed fans will remember that Michelle’s latest Instagram post is actually a throwback from the 2014 Logie Awards.
Perhaps realising that she had led her fans up the garden path, when one fan wrote: “You look beautiful. Are you guys getting married?” Michelle replied: ‘Happy as we are,” followed by two love hearts.
Michelle and Steve have been in a relationship since 2013 and share son, Axel, three together.
