Sienna Miller Sues over Tryst Photos
The actress accuses them of breach of privacy and has filed suit in London's High Court, her legal representatives confirm to PEOPLE.
Miller and the law firm of Carter-Ruck are taking aim at the photo agency Big Pictures and News International, which publishes the News of the World and Sun newspapers, which ran a series of stories and (scantily clad) pictures of Miller on vacation with the Brothers and Sisters star.
Getty, 33, recently announced his separation from wife Rosetta, mother of his four children.
In December, Miller, 26, won a judgment of about $75,000 against The Sun and The News of the World for publishing "highly intrusive" photos of her while she was filming a nude scene for the movie Hippie Hippie Shake. It's believed to be the largest fine ever levied for a photographic invasion of privacy in the U.K.
