The former The Only Way Is Essex star took to Instagram on Wednesday to answer some questions from her followers.
One person asked: "Do you love your own child a lot more than step children? I fear this will happen to me".
Kate wrote: "People ask me this a lot, and I can only speak for myself as everyone is different...
"I love all four children equally and I will never see any difference between my biological and non biological children.
"Lorenz, Tate, and Tia taught me what it feels like to love a child way before I had Cree.
"We worked so hard as a family to get to where we are now, and I take huge offence if anyone even suggests I would love Cree more than them.
"We have been through A LOT as a family, and that I believe has cemented my love for them so deep that the fact we are not blood is not important."
Kate and Rio exchanged vows in September 2019 and welcomed their son Cree in December 2020.
Rio's late wife and the biological mother to Lorenz, 14, Tate, 12 and Tia, nine Rebecca passed away in 2015 aged 34 following a battle with breast cancer.
Kate has previously slammed social media trolls who criticised her for referring to Rio and her stepchildren as "family."
Taking to Instagram to share a sweet throwback snap from the summer, she said: "One of my favourite days of this year, out at sea with the family .... no worries, happy & stress free."
And while most of Kate's followers wrote comments of support and well wishes, one troll hit out at Kate for her choice of words.
"Ooof. Rebeccas family. I'm all for stepmoms etc. And you've stepped into a massive hole. But those kids are Rebeccas," they said.
"And they'll not thank you for saying otherwise xx apart from that you are a lovely lovely girl. But, those wedding letters to "your" kids was terrible. Imagine if you were her looking down, or her mum n dad... not cool. Xx."
On seeing the insensitive comment, Kate replied: "Wow. Very very narrow minded. Rebecca is there mum & forever will be - a mother can never be replaced. But let me clarify WE ARE family, families aren't just about blood, but who is there for us and loves us unconditionally.
"Please think before you speak, are all foster & adopted children family less?! Of course not. Family is about love and choosing to be there for one another.
"We are family by CHOICE it's so sad you don't understand, let's hope you never have to go through such heartache to get it."
