Jerry Hall filed for divorce from billionaire husband Rupert Murdoch on Friday, citing "irreconcilable differences," six years after the pair married. The 66-year-old model sought unspecified spousal support and attorneys fees from 91-year-old media mogul Murdoch, in a California court filing. Hall said in the petition filed with the Los Angeles Superior Court she was "unaware of the full nature and extent of all (Murdochs) assets and debts, and will amend this petition when the information has been ascertained." She also asked the court to terminate its ability to be able to award support to Murdoch. Halls attorney, Ronald Brot, did not immediately respond to Reuters request for a comment. Murdochs legal representatives could not be reached outside of business hours. Murdoch and Hall married in a low-key ceremony in central Londons Spencer House in March 2016. It was Murdochs fourth marriage. The New York Times reported in June that the expected divorce would be unlikely to alter the ownership structure of businesses he holds stakes in. Murdoch, chairman of Fox News Channel parent Fox Corp, controls News Corp, publisher of the Wall Street Journal, through a Reno, Nevada-based family trust that holds roughly a 40% stake in voting shares of each company.
