Cami, who has a close bond with her mother, is one of four daughters and has said she was the last one of her sisters to try and forge a relationship with him.
But after failing to see eye-to-eye, the US model has given up hope.
Speaking to The Sun ahead of her CBB stint, Cami had said: "My dad can just f*** off. He's alone for a reason - he's not a good person."
Last week, we told how Cami's older sister was killed by a career criminal who was being chased in a car by police.
Cami, who is nine years younger than her sister, was so devastated by her death that she has gone on to study law at college.
While chatting to the newspaper, the CBB star also revealed that her sister was feuding with their father at the time of her death.
She added: "You would have thought he would have learned not to fight with his kids. But he hasn't."
Meanwhile, last night saw Cami escape nomination following a live twist in the show. Katie Hopkins, Nadia Sawalha, Perez Hilton and Alicia Douvall were all up for the chop, but Katie Price was told to save one and replace them with another housemate.
Mum-of-five Katie decided to save Katie H and chose to put Calum Best up in her place. The next eviction will take place this Friday and no doubt Cami is hoping Calum doesn't leave.
Earlier this week, Calum and Cami were shown getting pretty giggly and close after a few drinks.
