The pair kicked off at one another following Brandi and Jemma trashing the bathroom in the house the night before.
In last night's highlights we saw Sandi fume over the pair's actions, telling Amelia and Paul: "They are taking the p*ss! It’s petty! It’s disgusting!”
Yesterday, Sandi and Brandi came to blows as Brandi approached Sandi: "I think we should have a chat."
But Sandi replied: "I don't want to chat with you, Brandi. Me and you don't need to have a chat. Why do you want to have a chat?"
"Obviously you have an issue with me and I don't know what it is..." Brandi said before things kicked off.
"You will never draw me out, baby," Sandi hit out, "I don't need to draw myself out, I say it as it is. You hide and go and do stupid things like a child, Brandi."
Brandi reacted: "I will be who I want to be. I can be whoever I want."
Sandi told her: "You can't, you can't be a proper woman, Brandi."
"And not everyone has to do you all the time," Brandi responded.
"I don't know you... Sandi began before Brandi interjected: "Yeah, you don't know me, you don't know me and now you're running away..."
As Brandi chased after her, Sandi shouted: "You're meant to be like you're Brandi from America, babes. You just don't know, you ain't got a clue. I can't draw it out but you're doing it right now. Go and run and get some more stuff and go paint on the window in the bathroom.
"Big Brother had to shut the bloody blinds to go and clean the bloody window. Your children can do better games than you, babes "
"If I want to be immature I can be immature!" Brandi said. "Does it really matter if there's something on a window? Does it really f**king matter? What did it do to you?"
"Kiss my butt, kiss my butt!" concluded Sandi.
