"Soon-Yi was 8 years old when adopted by Ms. Farrow and the conductor Andre Previn during a trip to Korea.

"Ms. Farrow, who starred in many of Allen's films, was his companion for more than a decade, although, as Allen has pointed out, the couple never lived together, and spent their nights at separate homes. In 1992, the relationship between her adopted daughter and Allen came to light when she discovered nude pictures of Ms. Previn, who was then 21, in Allen's apartment."

Keep in mind that Allen did NOT adopt the young woman; she was the adopted daughter of Farrow and Andre Previn. I don't know how old she was when Allen and Farrow married but she was NOT a young child.

I've never even seen a film of Woody Allen's. Neither am I holding a brief for him but fair is fair.
