Lark Previn died Christmas Day at New York Methodist Hospital in Brooklyn, the medical examiner's office said. No cause of death was given. A cremation was held Tuesday at Brooklyn's Green-Wood Cemetery.
Lark Previn was born in Vietnam in 1973. She was one of three children adopted by Farrow and her then-husband, conductor Andre Previn. The couple also had three biological children.
Representatives for Farrow and Previn didn't immediately return calls seeking comment.
Farrow adopted two children and had a biological son during her relationship with Allen. She starred in several of Allen's movies during their relationship, which ended in 1992 when she discovered that Allen was having an affair with her adopted daughter Soon-Yi, then 22.
The bitter custody battle that followed featured accusations by Farrow that Allen had sexually abused adopted daughter Dylan, 7. Allen was exonerated of the abuse charges but Farrow won sole custody of the children.
Soon-Yi Previn married Allen, who is 35 years her senior, in 1997. They have two adopted daughters.
The Farrow-Allen custody fight featured court testimony that Farrow favored her biological children over her adopted children, including Lark. A movie producer testified on Allen's behalf that Lark was viewed as a "scullery maid" who "did most of the chores." Farrow's supporters said she was a loving mother to all her children.
