Casey's beloved hound Floyd died on the night the glamour model entered the CBB compound, and she didn't find out he had gone until after she was evicted.
The star has now told fans the sad story after Instagraming a photograph of herself holding Floyd's paw and offering him a kiss while at home.
Alongside it, Casey revealed: "My baby boy doggy Floyd, he passed away the day I walked into the house :( I didn't know until I came out :(
"I miss him sooo much. Love you bubba xxxxx #Doggy #AmericanBulldog #kisses #cbb."
Casey has been inundated with messages of support from fans. One commented: "So sorry for your loss, he was so beautiful. Hope you're alright xxx."
