The celebrity tattoo artist has always been thrown into the spotlight for her controversial opinions.
She'll start a debate on just about anything she knows gets people riled up.
While she may be able to get away with some of her opinions, some of her comments could get her and her multimillion-dollar cosmetic brand in deep trouble.
Kat became famous after starring on TLC's Miami Ink, a reality show about a tattoo studio in the bustling city.
After an alleged fall out with her colleagues, she starred in her own spinoff, LA Ink.
She has sparked outrage over things like naming her new shade of lipstick "Underage Red," wearing a Satanic wedding dress, and all the celebrity feuds she's been involved with.
In May 2018, the 36-year-old announced she's expecting her first child with her husband, Leafar Seyer.
Fans congratulated Kat on this new milestone, but now they're worried about the baby's well being after the tattooist's recent Instagram post.
The beauty mogul knew she would be "bombarded with unsolicited advice" on the way she chooses to raise her child, but that didn't stop her from expressing her opinion.
In the post featuring her baby bump, she shared her plans are to have a "natural, drug-free home birth in water with a midwife and doula" and raise "a vegan child, without vaccinations."
Many are applauding Kat's decision
"Vaccinated kids are the ones spreading measles!!" someone warned. "How can a child pass on measles if they've never even come into contact with it."
"It's so easy for people who don't do their own research to have 'STRONG' opinions about wanting to do something natural and be healthy! Do what's best for your baby.. that's all that MATTERS!! ... Those of us who actually understand your decision because it is your choice will always support you mama," an Instagram user commented.
But others say she's putting lives at risk
"You are literally risking, not just your child's life, but everyone around them," someone argued. "You are playing with something you clearly don't understand, and society, and your baby, will suffer for it. Vaccines aren't just safe, they are imperative to helping create a healthy world."
According to the Centers for Disease Control and Prevention, there's overwhelming research that vaccines "help develop immunity by imitating an infection, but this “imitation” infection does not cause illness.
Instead it causes the immune system to develop the same response as it does to a real infection so the body can recognize and fight the vaccine-preventable disease in the future."
UK-based beauty blogger Caroline Hirons is another one of Kat's critics.
After her 23-year-old son contracted mumps, she's been quite vocal on the importance of vaccinating babies.
"[My son] lost over two stone in weight. Without intensive medical intervention he would not be here. Now imagine he was a baby. Or someone with a compromised immune system. When I see people like @thekatvond using their platform to promote raising her unborn child ‘without vaccinations’, I want her and the drones of ill-advised people underneath...to see and know that this is the reality of ‘benign diseases’."
While most users argued back and forth over Kat's stance on vaccinations, someone raised a good point about Kat wanting her child to become a vegan.
"Is your baby not going to drink your breast milk? That's absurd. Diets are never a good idea for healthy kids. They should be eating foods from all the food groups to strengthen their immune system."
