Sienna MillerBritish tabloid News of the World has angered yet another celebrity by allegedly hacking into their cell phone data. This time, it's Sienna Miller, who is set to join the fight in suing the Rupert Murdoch-owned newspaper.

The Guardian reports Miller is taking legal action against the tabloid, which is already fending off similar claims by public figures like Steve Coogan and Chris Tarrant, for allegedly hacking into her phone and listening to private messages.

The move came after Miller, 28, discovered that the newspaper's private investigator, Glen Mulcaire, had acquired her cell phone numbers, account number and pin in order to snatch her voicemails.
