In 2004, the G.I. Joe star was targeted by a private investigator working for the now-defunct newspaper, who illegally intercepted her private voicemail messages to acquire information about her relationship with then-boyfriend Jude Law.
Miller sued over the controversy and was awarded $160,000 (£100,000) in damages in May (11) after editors accepted responsibility for invading her privacy, but the actress confesses the entire incident prompted her to question her most trusted friends and family.
During an appearance on U.S. breakfast show Today on Thursday (15Sep11), she said, ""At the time I was incredibly paranoid. Stories were coming out that nobody knew about, no one except my mother, my sister, my boyfriend and my best friend.
""And, you know, there were times when I would sit down with those four people and accuse one of them of sending (the paper) stories. And I also, it's terrible, (but) I would tell my best friends things and see if they came out (in the press), and they never did.""
And even though the lawsuit has been settled, Miller insists the fallout from the scandal will be long-lasting.
She adds, ""Everything is compromised enormously. It had a huge impact on relationships, friendships, career, all sorts of things. But on a personal level, just that feeling of violation... It was bad for me.""
