A cause of death has now been released for Diane Ladd, the Oscar-nominated actress and mother of Laura Dern, who died earlier this month at age 89.

According to a death certificate obtained by People, Ladd died of acute on chronic hypoxic respiratory failure on Mon., Nov. 3. She was cremated a week later, on Mon., Nov. 10, the outlet reported.

Ladd’s career spanned more than seven decades, earning her acclaim for roles in both film and television. 

She received three Oscar nominations, including for her performance as Flo in the 1974 classic "Alice Doesn’t Live Here Anymore." 

She later earned another nomination for playing a volatile mother opposite Dern in "Wild at Heart" and a third for her work in "Rambling Rose."

Off screen, Ladd and her daughter shared a close bond. The two co-authored the memoir "Honey, Baby, Mine," which was inspired by heartfelt conversations they began having after Ladd survived a serious medical scare in 2018.

Originally misdiagnosed with a lung condition caused by pesticide exposure, Ladd recovered after Dern insisted on a second opinion.

Ladd’s personal life was shaped by both triumph and tragedy. She lost her first daughter, Diane Elizabeth, in a swimming accident at 18 months old. Ladd was married three times, including to actor Bruce Dern, Laura’s father.
