The star is so hung-up on her conspiracy theory she has told pals she believes Peter is still obsessing over her and trying to find out details about her private life – in particular her romance with Leandro Penna.
Meanwhile, Peter, 39, has blasted his ex-wife's theory as complete nonsense and says he doesn't want ANY part of her life.
A source close to Jordan, real name Katie Price, 34, told Reveal: "She has this idea that Pete is watching her every move and has ways of finding out things about her.
"She doesn't really trust that many people around her as she suspects some of them are still in contact with Pete."
And it's no secret that Jordan is constantly paranoid about her friends selling out on her.
She's been very vocal about her former pal Jamelah Asmar ditching her for Pete, and at her wedding to Alex Reid in 2010, she even asked two friends to leave after accusing them of leaking information about the nuptials.
