The couple, who were married in 1999, have two daughters together. This was Murdoch's third marriage to end in divorce.
It was reported that his divorce from second wife Anna Murdoch, in 1999, cost him $1.7 billion, one the largest marriage settlements on record. According to Forbes, Rupert Murdoch's current net worth is $11.2 billion.
Murdoch is 82. Deng is 44. Their divorce was first reported by Deadline.com.
In 2011, Deng rose to her hu*****and's defense by smacking a protestor who threw a shaving-cream pie at him during Murdoch's hearing before British parliament. Murdoch was being questioned at the time about his newspapers' practice of phone-hacking.
Deng, a Yale graduate who was born in China, met Murdoch while working as an intern at Star TV, part of News Corp., in 1996. "I had heard of him before but never seen him," Deng told theChina Daily in 2008. "My boss assigned me to introduce the Chinese market to him. He was very interested in Chinese culture and we talked a lot."
The couple and their two daughters Grace, now 12, and Chloe, 10, lived in a $44 million Fifth Avenue penthouse previously owned by Laurance S. Rockefeller. They also had homes in Los Angeles, London, Canberra, Australia, Carmel, Calif., and Centre Island, N.Y.
Deng was 18 when she met her first hu*****and, Jake Cherry, 48, who sponsored her on a study-abroad program in California. She lived with Cherry and his wife after meeting the couple in Hong Kong. After Jake and Joyce split up, she was married to Cherry for about three years.
