Embattled publishing tycoon Rupert Murdoch has filed for divorce from his wife of 14 years. The billionaire, who shares two young daughters with Wendi Deng, filed papers to end their union at the New York Supreme Court on Thursday (13Jun13). A spokesperson for the 82-year-old media titan confirmed the news, stating, "The relationship between the husband and wife has broken down irretrievably." The split comes just two years after Deng made headlines in 2011 when she aggressively defended her husband from a pie-throwing protester during a British parliamentary committee hearing regarding the News Corp. phone hacking scandal. Murdoch has been been married twice before - he divorced Anna Torv one month before he wed Deng, and he separated from wife Patricia Booker in 1967.
