One insider said: “Jamie Lynn has got decades of history and bad blood with Britney to rake over and has laid out her feelings pretty clearly in her own book. Writing in The Woman in Me, the pop superstar claimed she’d reached out for help when she was put into a rehab centre for months against her will, but that her sister had told her to “stop fighting it”.
In her recent memoir Britney, 41, branded Jamie Lynn a “total b***h” for not helping her more. Now producers believe mum-of-two Jamie Lynn, 32, will prove fascinating when she jets in to Australia for the ITV show.
The actress, 32, has long had a tumultuous relationship with her world-famous older sibling, who was held for years in a strict conservatorship by their father.
