It's clear Jess has always disliked Vanessa, even admitting she told her brother from the get-go that "she's trouble" and he "needed to get rid of her".
Her hatred for Vanessa later reached fever pitch when she discovered the businesswoman had also dated her ex-boyfriend, MAFS contestant Dan Webb.
"She dated my brother and then she went to Dan and one of my other ex-boyfriends," an angry Jess continued. "They were only together for a few months but then she went to my ex Stephen. I was confused and shocked."
Known for her controversial carryon, Jess is also feuding with The Bachelorette's Angie Kent. Yesterday, the outspoken MAFS contestant unleashed on the former Gogglebox star after she branded her as "super trash".
“She thinks she's better than us. She got her start by drinking on TV [Gogglebox] and now that she’s the Bachelorette, she wants to look down on people. Please, she’s dating 21 guys at once. She’s just a bogan and a hypocrite," Jessika told Daily Telegraph's Confidential.
Jess's savage response comes after Angie said MAFS is the trashiest reality TV show on our screens— a brutal comment the controversial star didn't take too kindly to.
"Yes, I had an affair but I own what I did,” she said. “She just wants fame — she’s been on Gogglebox, I’m a Celebrity and now The Bachelorette … as if she couldn’t find love already?"
