Hamilton gave up her privacy on Thursday when she entered the secure property in London for the programme, alongside other famous faces including former The Hills stars Heidi Montag and Spencer Pratt.
Following the show's launch, the property was divided in two, and Hamilton was among the contestants confined to a dank basement with no windows and no running water - but she was chastised by TV bosses for likening the house to a Nazi concentration camp.
She was put up for eviction by her fellow contestants on Sunday, and Hamilton threatened to pack her bags and quit the series during a rant to cameras in the Diary Room.
The star raged: "Can you bring my suitcases up please? I'm leaving. You've completely broken me. This was a chance for me to get my life back on track... and you've sabotaged me the whole way along.
"I just feel totally broken, I want to go home. I was really into helping you make this a great show but you've just sabotaged me, because you've completely taken away my dignity and my trust. You've broken me. Congratulations."
Hamilton eventually decided to remain in the house, and declared: "I'm staying but I won't be close to the women in the house."
Hamilton, Pratt and Montag, as well as jockey Frankie Dettori, are nominated for the first eviction, which will take place on Wednesday.
