Former 'Sex and the City' actress Sarah Jessica Parker says her four-year-old son James Wilke has begun asking questions about what it means to be gay. Sarah - who is married to fellow actor Matthew Broderick - said: "He's very interested in what being gay is because so many of our friends are gay. "When talking around your child you have to think very carefully and you have to be prudent about you're choice of words. You talk about people looking for happiness and fulfilment in their lives and how all families are different and look different. "You're forced to really consider your answers. You're forced to think a lot about what you're saying and how you're saying it - even the tone." Sarah took James to his first celebrity party last week. The actress and her son attended the launch party for stylist Serge Normant at New York's John Frieda salon. She said: "He loves Serge. He wanted to come." Ref: Female First (m)
