Katie Price has reportedly lined up Sir Paul McCartney’s divorce lawyer, Fiona Shackleton, to help represent her when she files for divorce from Peter Andre. Mrs Shackleton also represented the Prince of Wales when his marriage to Diana, Princess of Wales was dissolved and more recently, she helped the singer Madonna formalise her separation from Guy Ritchie.  Katie is reportedly determined not to allow Peter a share of her £40m fortune, while Andre is said to have told friends that he insisted on a pre-nuptial agreement before they married.
