Mia Farrow found nude photos of Soon-Yi at Woody Allen’s home

Mia Farrow found out then-boyfriend Woody Allen was involved in a relationship with her adopted daughter, Soon-Yi Previn, after she discovered “pornographic” photos of Previn at Allen’s Manhattan apartment, the actress revealed in a new bombshell docuseries.

“[I] was at his apartment because I wasn’t working that day,” Farrow explained in the new HBO documentary series “Allen v. Farrow,” according to HollywoodLife.com.

“So, I took one of the kids over after we left a coat over there, and there by the side of the phone, to the right of the phone, was his stack of Polaroid pictures, of pornographic pictures of a woman, a girl.

“And I picked them up and I realized all of them were of Soon-Yi. It was my own child,” the “Rosemary’s Baby” actress said.

Farrow said the discovery left her “struggling to breathe.”

“She was in her first year of college and they were all just like… They wouldn’t put them in ‘Playboy.’ They were like, I don’t know, ‘Hustler’ pictures or something. [They] really were raunchy pictures and I, you know, I… I remember struggling to breathe. I remember getting my son, trying to put his coat on, trying to do the buttons,” she recalled.

“I took the photos and I put them in my pocket and I was leaving and then I just realized that I don’t even think I could push the elevator button. I was just like shaking. And I took my child home and I locked the door,” she said.

Farrow and Allen had been dating for more than a decade by the time she discovered the photos of Previn — the adopted daughter of Farrow’s ex-husband, musician André Previn.

Previn, 50, is now married to Allen, 85. The pair tied the knot in 1997.

In the documentary, Farrow, 76, explains how she confronted her daughter about the photos.

“Soon-Yi was home and I remember saying. ‘I found the pictures,’” Farrow said. “And she said, ‘What pictures?’ And I said, ‘The pictures Woody took.’ And she started crying and I started crying and I’m like, ‘No, no, it’s not your fault.’ And she was beside herself.”

The actress said Allen then came over to her apartment to discuss the matter, insisting he “lost control” and “made a mistake.”

“And then Woody was there for like four hours, just talking and talking and talking,” Farrow said.

“And first he said, ‘I’m in love with Soon-Yi. I would marry her.’ And then he said, ‘No, I just said that. It’s something I thought of in the car. I thought it would make it better if I put it that way. No, I love you.’”

“Then it was all that for four hours — ‘I made a mistake, I lost control.’ Blah-blah-blah. I didn’t know what to think. I just needed him to get out,’” she said.

The docuseries also examines the sexual abuse allegations against Allen by daughter Dylan Farrow.

The Academy Award-winning director and his wife released a statement Sunday, shortly after the airing of the first episode of the doc, slamming the sexual abuse allegations against Allen as a “hatchet job” that was “riddled with falsehoods.”
