Things got explosive in the house yesterday when the pair bickered and Jemma brought up Paul's son.
It all started when Brandi told Jemma about a comment Sandi apparently told Paul; “She doesn’t like you either. She thinks that we’re immature and she thinks that we’re a mess.”
Jemma walked into the garden to confront Paul about the allegation, and mentioned his son.
It set Paul off as he stormed into the living room: "Why are you bringing my son into it? Look at the state of you!"
"Look at the state of you, sort your head out!" Jemma hit back from the garden.
Paul then returned: "Go drink your f**king drink!"
"At least I can handle it!" Jemma retorted.
"Why are you going so low?" Paul said, confronting Jemma in the garden. "What have I ever done to you?"
"You're a s**t stirrer!" Jemma claimed.
"What have I ever done to you?!" Paul repeated as the pair began to square up to one another.
"Bring it, bring it!" Jemma
goaded goated before Big Brother stepped in to split the pair up.
Paul and Jemma's row wasn't the only one in the house yesterday.
Sandi Bogle and Brandi Glanville also locked horns after Brandi and Jemma trashed the bathroom.
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.
