Sarah Jessica Parker's Passion

Since leaving Sex and the City, Sarah Jessica has also been spending lots of time with her 4-year-old son, James Wilke, who is full of questions! "He's unbelievable," she says. "He has a lot of questions about science and gravity." Sometimes, Sarah Jessica says, she leaves answering those up to his dad, Matthew Broderick. "My husband, who is a real brainiac, can take over."

Aside from loving music, theater and his superhero capes, Sarah Jessica says James Wilke is also very curious about social issues—like what being gay means. "His school is a school in New York City and so there's people that have children who have two mamas and two papas, and so it sort of authentically happens, this conversation," she says. "You think very carefully and you're prudent about the choice of words, and then you talk about people looking for happiness and fulfillment in their life and how all families are different and look different."

As a mom, Sarah Jessica says that she often thinks about the answers she gives her son. "You're forced to think a lot about what you're saying and how you're saying it and even the tone," she says.

Still, that doesn't make the tough questions any easier! "He asked me where babies come from," she says, "and you find yourself saying, 'You know, your papa will be home at 6:00, and he's far better equipped to discuss that particular part of your body than I am.'"
