Ashleigh and Lauren have had long-standing tension in the house, with the Essex barmaid seemingly believing Lauren is a threat to her relationship in the house with Luke Scrase.
Ashleigh and Shievonne's latest rant was based around a belief that Lauren is not sharing her cigarettes.
"The selfishness is unbelievable. I just can't take no more. Double personality," said Shievonne
"She better keep my name out of her mouth."
Later, Ashleigh said: "I'm so pissed off right now that they are smoking and not giving us any... I hate [Lauren] with a passion."
Looking at Lauren and others in the garden, Shievonne said: "They are blatantly lying. They are mugging us off right now. They are actually laughing rolling!"
Lauren appeared aware of their issues, claiming that the duo were "double teaming" her and describing the pair as "pathetic".
