The former TOWIE star took to Instagram on Wednesday to announce Blended, as network for families meshed together by 'a break up, fostering, adopting, loss' or other circumstances, following her own experiences as a step-parent.
She detailed the difficulties she faced when she became step-mother to her husband Rio's kids, Lorenz, 15, Tate, 13, and Tia, 10, and how their family has been made complete by her biological son Cree.
In her candid post, Kate spoke about becoming a step-mother after the tragedy of Rio losing his wife and the kids losing their mother Rebecca Ellison, who passed away in 2015, two years after being diagnosed with breast cancer.
