Newspaper mogul Rupert Murdoch, 91, and model, and actress Jerry Hall are divorcing, the New York Times reported Wednesday, citing two sources close to the couple.

It will be the fourth divorce for Murdoch, whose fortune is estimated at $17 billion.

Bryce Tom, a spokesman for Murdoch, declined to comment on the story when contacted by AFP.

The New York newspaper assures that it is unlikely that the tycoon's divorce will alter the structure of his empire, managed by a trust in which he shares a vote with his four eldest children: Lachlan, Elisabeth, James and Prudence.

is empire's media outlets include the Fox News television network and The Wall Street Journal in the United States, the English newspaper The Sun, and the Sky News television network in Australia.

The billionaire and Hall, 65, who was married to Rolling Stones vocalist Mike Jagger with whom she had four children, married in March 2016 in London. Then Murdoch wrote on Twitter that he was "the luckiest and happiest man in the world."

Murdoch's first wife was Patricia Booker, an Australian stewardess, whom he divorced in the mid-1960s, before marrying Anna Torv, a journalist, whom he divorced in 1999 after more than three decades of marriage.

He then married Wendi Deng, an entrepreneur and investor of Chinese origin, whom he divorced in 2013.
