Every parent has the old "Birds and the Bees" talk with their children in different ways. Some parents are straightforward, some get really uncomfortable, and others -- like Sarah Jessica Parker –- create elaborate lies.
Speaking with David Letterman on The Late Show on Monday, the Sex and the City star explained the intricate lie she told her two-year-old son James when he first asked her where babies come from.
"At that time I told him that he had one seed," Parker recounted. "And there was a young woman named Mary who he would meet in sophomore year of college. She was going to be very smart, and lovely, and came from a nice family. And that he would choose Mary to give his seed to, but he had only one."
As it turns out, Parker had misunderstood her son's question, and he hadn't even been asking about reproduction at all.
"He had a little cloth that he called his 'baby' and he would hold it up to his face, and he asked me, 'Where does my baby come from?'" Parker said, explaining her confusion. "I said, 'Oh my god! Where do babies come from?! I'm not prepared!' I thought I had a good 10 or 12 years!"
"So I thought about what I would like for him," she added. "Which is that he have one seed, and that he should choose wisely."
Parker, whose son is now 12, is also the mother of two daughters, Marion and Tabitha, who were born via surrogate in 2009.
