Jason Schwartzman and his wife, Brady Cunningham, are expecting their second child. Us Weekly exclusively confirmed that Cunningham is pregnant and due in the spring.

The couple's daughter, Marlowe Rivers Schwartzman, is now three years old. "Marlowe is super excited about becoming a big sister and they are thrilled to be adding to the family," a source explained.

As they did when Marlowe was born, Schwartzman and Cunningham plan to wait until birth to learn the sex of the baby. In a previous interview with Us Weekly, the actor explained their choice to keep the baby's sex a surprise and described it as leading to "a great moment."
