Parker and her husband, Matthew Broderick, welcomed their son in 2002. He has two twin sisters, 6-year-old Marion Loretta Elwell and Tabitha Hodge, and in an interview last week with Buzzfeed, the actress opened up about her kids.

"My son is 13. So I would say probably getting news that my daughters were arriving," she said, recalling her best memory of the past 10 years. "Sharing it with my son, as we ran to go meet them, hearing what he had to say about this introduction was pretty incredible."

"He was so excited," Parker continued.
