Mia Farrow, a popular actress, has received some sad news.

Mia Farrow issued an emotional letter on Twitter in reaction to the renewed interest in her family due to the HBO documentary Allen v. Farrow, in which she revealed the deaths of three of her children and referred to their deaths as “unutterable tragedies.”

While the allegations that Dylan Farrow’s adoptive father, Woody Allen, sexually assaulted her when she was seven years old are central to the four-part series, some viewers have chosen to focus on the lives of Farrow’s other children rather than on the allegations that Farrow has made against Allen.
