Last night, it yet another row between the two housemates, Perez was seen branding Katie "homophobic" after she told him to "man up" during a Question Time-style Big Debate task.
Katie was horrified at the suggestion, denying she is no such thing, and is seems the public are backing her all the way.
Having gone into the CBB house as 'Britain's Most Hated Woman', it appears Perez's behaviour has dramatically swayed people's opinions of the outspoken star.
Following their argument last night, many fans were quick to give their views online.
One commented: "It's quite a remarkable thing when Perez Hilton has solely changed my opinion on Katie Hopkins, so much so that I almost actually like her now."
Another added: "Disliked Katie but love her now after the show. Liked Perez Hilton but cannot stand him now- get off my TV! Ps: Katie Hopkins for Prime Minister!! lol."
One viewer even said: "She may be a number of things but highly doubt she is homophobic...she dislikes him for his horrible personality not because he's gay!!"
Others, however, have branded Perez and Katie "as bad as each other".
Tonight, Perez faces eviction in the live show along with Calum Best, Nadia Sawalha and Alicia Douvall. According to the bookies, Nadia is the favourite housemate to be given the boot.
Meanwhile, elsewhere in the house, Katie Price has left her brother Danny seriously red-faced after speaking so openly about her sex life. Oops!
