Josie is “jealous” of Caoimhe’s increasingly close relationship with John James.
The curvy Bristol girl told the angry Australian he should be wary of “smarmy” Caoimhe during a heart-to-heart chat in the bathroom in the early hours of this morning.
Josie said: “I’m not stupid, I know she’s trying to wind me up. She’s a smarmy little b***h on the quiet. She thinks it’s funny, but it’s not."
Josie also told John James she thought the Irish girl brought out a "negative" side to him and alienated him from the rest of the group.
Although Josie has confessed to other housemates she has a crush on John James, the blonde hunk told Dave in an earlier conversation he isn’t attracted to her and wouldn’t want to have a relationship in the house anyway.
Dave said: "She thinks a lot more of you than you realise."
John James disagreed with him, and replied: “It’s more of a brother and sister relationship.”
