Last week, the 31-year-old liked an Instagram comment from a fan who implied that she was way out of Locky's league.
"You're too good for him tho!!!" the fan wrote in reference to Locky.
While it's not exactly proof, it's pretty damning nonetheless and strongly suggests that the pair did not end up together.
Now, there are some other reasons that the Merlbournian nurse would have done this despite actually having 'won' the show. It's possible that Irena does win but that the romance was short-lived outside of the show, like so many couples before them.
But that theory wouldn't align all that well with Locky's most recent interview, in which he told Perth Now that he is "in love" with someone. However, it could be the case that he has since found love elsewhere.
Meanwhile, Irena has been a fan-favourite since the beginning and her win has been pegged through online betting stats that have her as the front-runner.
Whatever the results may be, let it not be another Honey Badger situation.
