Calum Best is to be shown slamming Perez Hilton in tonight's episode of Celebrity Big Brother, claiming the blogger has "72 different" personalities.
Finally losing his cool, Calum has a heated discussion with Perez following Cami Li's surprise eviction.
Perez responds to Calum asking "What's your f**king problem?" by saying: "I don't even like you, I'm just living with you", going on to accuse Calum of playing a game to stay in the house.
Calum replies: "I am a genuine, honest, chilled out person ... No one likes you because you act like a d**khead!"
He goes on to add that the blogger plays up to the 'Perez Show' with his "72 different characters", stating: "That's why no one in this country likes you."
When Perez says he was never his "mate", Calum snaps further, adding: "Shut the f**k up you f**king power tripper. You're a piece of s**t and nobody likes you! Don't bother talking to me for the rest of the time, you c**t!"
Michelle Visage then steps in to try and smooth things over before later congratulating Calum on standing up for himself.
Kavana wades in on the conversation and says: "Meek and mild Perez has gone back to absolute f**king manipulative crazy lunatic and is riling up the gentlest, kindest most real people in the house."
'Celebrity Big Brother' airs tonight (03.02.15) at 9pm on Channel 5.
