Jude Law's ex-wife received $80,000 (£50,000) from Rupert Murdoch's now-defunct News of the World after it emerged she had been targeted by a private detective working for the publication.
She had become paranoid her close pals and relatives were responsible for stories about her personal life appearing in the tabloid - and admits she was "glad" when she realised the information had actually come from the interception of her voicemail messages.
Frost tells U.K. TV show This Morning, "I was glad I found out I was hacked, in a way, because I never found out how all this information was getting into the papers. There was so much distrust between me, family members, friends... It was a distressing time for so many people... it's just such an awful, immoral thing to do."
