The aunt of North Korean tyrant Kim Jong-un suffered a fatal stroke during a heated phone call with the dictator, just days after he executed her hubby, according to a highly placed defector.

Kim shocked the world last year when he had his mentor and uncle, Jang Song-thaek, suddenly put to death — and leaving the fate of Jang’s wife and the dictator’s aunt, Kim Kyong-hui, in question.

Kim Kyong-hui was on the phone with her tyrannical nephew when she suffered a stroke, defector Kang Myung-do told CNN. She was rushed to the hospital, where she later died, the defector added.

The cable news network said it could not independently verify Kang’s dramatic account. Kang is the son-in-law of former North Korean Prime Minister Kang Sun-san.

The fate of Kim Kyong-hui has been the source of wild speculation since Jang’s date with the firing squad on Dec. 12, 2013.

The Wall Street Journal — citing defector Kim Heung-kwang — last week reported that the aunt fatally poisoned herself shortly after her hubby’s execution.

“She didn’t have the will to live,” the defector said.

Then back on Oct. 31, the South Korean newspaper JoonAng Daily reported that Kim Kyung-hui was overcome by grief, suffered a cerebral hemorrhage and has been in a vegetative state ever since.

JoonAng Daily cited defector Park Sang-hak, who said: “I was told she had a stroke over the shock of Jang’s death.”
