However, Jess has since cleared up the rumours by stating that she and Jake are only friends, telling Daily Mail that they were just merely catching up with a cheeky vino.
"I'm in a relationship with someone else," she insisted to the publication
But of course, the rumours—squashed or not—were quick to believe given the former AFL player's questionable past that has recently been revealed.
Prior to the show, the 32-year-old was involved in a cheating scandal with his ex-fiancé Paige, when friends of hers called him out on social media.
Taking to Instagram, one of Paige's friends said, "First of all LEL at 'EX AFL Star'", in retaliation to a news headline about Jake. Another friend also posted comments about his past behaviour, saying: "Good luck to his future. In the midst of it all finds it somewhere in him to apply for MAFS."
Of course, that was only the beginning with Paige herself coming out to publicly announce that she wouldn't be watching this season, adding she won't be "wasting" her energy with it.
"I am not watching MAFS and have no intention to. I don't want to waste my energy on it so please stop sending me everything you see," she wrote.
