"Just a question have you donated any money to the bushfire appeal?" a terse fan asked Jess who was infamously embroiled in a series of scandals during last season of MAFS.
As per usual, the Instagram influencer put the follower in their place, claiming she donated thousands of dollars to help those in need.
"Sure did. $5K to be exact, not that I was asking for recognition," she hit back, while also asking whether the troll had donated.
Many fans rushed to Jess' defence, praising the Perth native for setting the record straight with one user writing: "Yes girl! You don't even need to explain yourself but the clap back is real!"
Someone else chimed in saying, "Clap back game strong!" while another wrote: "You don't need to answer these questions!"
Her savage response comes days after Jess weighed in on season seven's cast of Married At First Sight, defending Hayley Vernon who has already been deemed the show's next villain. As rumours swirl the bodybuilder will follow in Jess's footsteps and cheat on her on-screen husband, she took to Instagram to ask fans of the series to be kinder to Hayley.
"You lot can be ruthless! Remember that your words can hurt or offend," the 28-year-old wrote. "I think she looks like a lot of fun and will no doubt bring the drama you all feed off when watching MAFS.
"Let's be a little kinder, guys. It costs absolutely nothing and this woman is about to be exposed to a lot of opinions."
