Josie's aunt has said that she is fearful of John James breaking her niece's heart when the show comes to an end.

Kay Gibson, 44, spoke to Now magazine about the house romance and her concerns for Josie.

"I fear John James will break her heart and she'll be devastated," she said. "Their relationship's bringing out her insecurities.

"She's giving herself a hard time about her looks and comparing herself to the slimmer girls in the house. I've tried telling her she doesn't need a man and that she needs to learn how to be happy on her own.

"Josie can't believe she's got John James but he isn't out of her league. She's brilliant and very attractive. He's bloody lucky she looked his way!

"I'm just concerned because she hasn't had many boyfriends and when her last relationship ended, it really upset her."

Josie recently told John James that his mum should "move in" with her Auntie Kay.
