The former EastEnders actress left the house on Friday and subsequently admitted that she was on a mission to outlast Kristina and Karissa, branding them arrogant and vicious.
Cassidy has since repeated her disdain for the Playboy models, claiming that they mocked her weight while in the house.
"Have just done an interview and have only just found out the twins said - 'someone thinner should do the shopping list'.. Get em OUT!!!" she wrote on Twitter.
She then went on to retweet a number of insulting tweets regarding the twins, which referred to them as "fake", "annoying", "up their own arse" and "nothing special".
Cassidy added: "Had the most amazing experience. Thank you so much for your support, I love you all. Everything happens for a reason! #watchthisspace xx.
"So weird not waking up in the house but amazing to wake up with my little girl. Thank u for all your amazing tweets xx."
