Smyth, who appeared on the 2013 series of the reality show, wrote that her recent 28th birthday threw her into “a tailspin”.
While recent rumours suggested Smyth was dating Bachelorette star Richie Strahan, Smyth’s post indicates that she is in fact single and looking for a partner.
She wrote: “I can’t even lock down a second Tinder date...In fact at this very second, as I write this, I have no partner, no job (my four-month contract at one of Melbourne’s top PR agencies has just ended) and as of Christmas, no home either (my housemates are getting married in January and weirdly, want the place to themselves. $100 says my room has a crib in it by Easter).
"Every single one of my friends are getting engaged...some are even having babies. On purpose...I'm going to die alone," she continued.
