Robert F. Kennedy Jr.'s estranged wife has died.
Law enforcement sources tell TMZ, 52-year-old Mary Kennedy was found dead in her Mount Kisco, New York home this afternoon.
The Bedford Police Department responded to the scene at approximately 1:36pm to investigate a possible "unattended death," meaning the death was not witnessed by anyone.
Mary and RFK Jr. were married in 1994. Robert filed for divorce in May 2010. Mary was Robert's second wife. The couple has four children together.
There are reports Robert F. Kennedy Jr. is currently dating actress Cheryl Hines.
Three days after Robert filed divorce papers in 2010, Mary was arrested on suspicion of DUI.
A spokesperson for Mary's family just released a statement, claiming, “We deeply regret the death of our beloved sister Mary, whose radiant and creative spirit will be sorely missed by those who loved her. Our heart goes out to her children who she loved without reservation."
