Movie icon Clark Gable's son has been exposed as a suicidal drug addict by his 19-year-old daughter. KAYLEE GABLE feels sure the late GONE WITH THE WIND star would be devastated if he could see his son, actor JOHN CLARK GABLE, throwing his life away. The teenager tells the new issue of US tabloid National Enquirer, "My father is dying from addiction to crack cocaine. "I know if my grandfather were alive today it would break his heart to see his only son killing himself with drugs. "He was just as good looking as his father, but now he's lost all his teeth and he's wasting away."
