Mia Farrow is speaking up about the loss of her three children who died while they were little.

On Wednesday, the 76-year-old actress and activist turned to Twitter to discuss the deaths of her daughters Tam and Lark, as well as her son Thaddeus, following “vicious rumors” that they were not mentioned in the recent HBO docuseries Allen v. Farrow.

“As a mother of fourteen children, my family means everything to me,” Farrow wrote. “While I chose a career that placed me in the public arena, most of my children have elected to live very private lives..”

“Few families are perfect, and any parent who has suffered the loss of a child knows that pain is merciless and ceaseless. ​However, some vicious rumors based on untruths have appeared online concerning the lives of my three children. ​To honor their memory, their children and every family that has dealt with the death of a child, I am posting this message.”

The Golden Globe winner, who has four biological children and ten adopted children and was formerly married to Frank Sinatra and André Previn, lost daughter Tam Farrow in 2000, daughter Lark Previn in 2008, and son Thaddeus Farrow in 2016.

Farrow, 76, went on to describe the events surrounding the deaths of three of her adoptive children, which she claims were caused by a combination of factors.

Tam died at the age of 17 from an overdose of a prescription drug “related to the agonizing migraines she suffered, and her heart ailment,” according to Farrow.

Farrow hailed Lark as a “extraordinary woman, a wonderful daughter, sister, partner and mother to her own children” after she died in 2008.

“She died at 35 from complications of HIV/AIDS, which she contracted from a previous partner,” she said. “Despite her illness she lived a fruitful and loving life with her children and longtime partner. She succumbed to her illness & died suddenly in the hospital on Christmas, in her partner’s arms.”

Thaddeus Farrow, according to Farrow, “was 29 and happily living with his partner.”

Thaddeus “took his own life” because a romance that appeared to be headed for marriage failed instead.

She wrote, “These are unspeakable tragedies. Any other speculation about their deaths is to dishonor their lives and the lives of their children and loved ones.”

“I am grateful to be the mother of fourteen children who have blessed me with sixteen grandchildren. Although we have known sorrow, our lives today are full of love and joy,” she concluded. “Everyone has their own battle to fight; their own sorrows that gnaw. I send you my best hopes and love.”
