Following the latest eviction, where Joe got the axe, things got very tense in the garden between Chanelle and Simone.
The pair clashed with Chanelle accusing Simone of 'coming for her' while Simone claimed Chanelle had been 'spreading lies' about her by branding her fake.
In a showdown in the smoking area, Simone told Chanelle "You can shout at me if you want. Go for it, smack me in the face if you want, I'll take it."
Chanelle replied: "I wouldn't. I know you're trying to provoke me babe, but I wouldn't do that to you because I don't need to do that to you."
Charlotte then piped up: "Well that escalated quickly."
Simone later accused Chanelle and the other housemates of ganging up on her and claimed a "bitter" Chanelle was 'going at her'.
Simone concluded: "For a person who's been bullied she's got a funny way of showing it."
In a second face off, Chanelle told Simone: "I've never bullied you, you came for me. I'm so nice to everyone and you come for me and you don't know me."
Simone replied: "You don't understand me, I've been in worse situations."
"Don't start with someone and then play the victim," Chanelle hit back.
Afterwards, Simone told Sue: "To me, she's a child and I am not and I'm not gonna get on her level to make myself look stupid.
"I can deal with the straight up but the mental, where going around making lies up about me and stuff to the whole house.
"She's trying to turn the whole house to go against me."
Meanwhile, Chanelle declared to Isabelle: "She can just f**k off, I'm done with her."
