"That bottom lip looks like it was stung by a bee. Not a good look," a user commented on underneath the photo.
Another even questioned if she was high because of her eyes. "What's happening with your eyes? You look high or something."
It's not the first time Jess has copped it from fans for her appearance, but it seems like she has taken a mature stance with her replies.
"That's your opinion... cool. I won't judge that just like you shouldn't judge my lips haha double standards. I also don't care for negative opinions so I don't know why people waste their time."
But Jess isn't the only MAFS star altering her appearance and proudly showing it off. Tamara Joy, from the same season, has recently given her fans a look at her brand new nose.
While Tamara has posted a few shots of her new nose on Instagram, her most recent is a profile view, without the swelling post-surgery.
She also wrote on her Instagram Story: "I love my nose."
Unfortunately, it hasn't been well-received by her fans.
"Oh babe what have you done!!!! Too much stuff done to your face, you looked so much better before," wrote one fan.
In March this year, Tamara admitted to Yahoo!: "I have had some cosmetic surgery. I’ve had my breasts [done] and I’ve got lip filler."
"People do it for all different reasons and I guess mine was just more so… I had a bit of a booty and I really wanted to balance that out, that’s why I did it,” she reveals.
However, it was just recently that The Daily Mail captured photos of Tamara with bandages covering her nose at Indigo cafe in Double Bay on Thursday, after her procedure with plastic surgeon Dr Michael Zacharia.
"If it makes you feel better about yourself, why not?" she continued.
