PRESS ASSOCIATION -- Sienna Miller says she planted false stories with friends in an attempt to work out why intimate details of her life were appearing in British tabloids.

The actress and former girlfriend of actor Jude Law, who was a victim of phone hacking, says the incident made her paranoid.

She told NBC's Today show in an interview that stories appeared in newspapers that only her mother, sister, boyfriend and best friend knew about, and she accused them of selling stories to the press.

Miller reached a £100,000 settlement with the News of the World, after it was found that her mobile phone messages had been hacked.

She said she also became suspicious when she heard people were leaving her mobile messages that she would never get.
