Jerry Hall has officially filed for divorce from billionaire husband Rupert Murdoch six years after the pair married.

The 65-year-old model and actress filed a petition in the Superior Court of California, citing "irreconcilable differences" as legal grounds for divorce.

In her petition, she also sought unspecified spousal support from 91-year-old media mogul Mr Murdoch and wants him to pay for her attorney's fees.

She said in the petition she was "unaware of the full nature and extent of all [Mr Murdoch's] assets and debts, and will amend this petition when the information has been ascertained."

Ms Hall's attorney, Ronald Brot, did not immediately respond to a Reuters request for comment.

Mr Murdoch and Ms Hall married in a low-key ceremony in central London's Spencer House in March 2016.

It was Ms Hall's second marriage and Mr Murdoch's fourth.

Ms Hall married Rolling Stones lead singer Mick Jagger in Bali in 1990.

But the marriage was later declared null and void by a UK high court judge in 1999.

Mr Murdoch was previously married to entrepreneur Wendi Deng, who he divorced in 2014 after 14 years of marriage.

They have two daughters.

He split from his second wife, Anna Murdoch Mann, a Scottish journalist with whom he had three children, in 1999.

He and his first wife, Patricia Booker, a former flight attendant with whom he had a daughter, divorced in 1966.

The Fox Corp chairman controls News Corp and Fox Corp through a Reno, Nevada-based family trust that holds roughly a 40 per cent stake in voting shares of each company.
