Jason Schwartzman is gearing up for baby No. 2! The Saving Mr. Banks actor and his wife Brady Cunningham are expecting their second child, Us Weekly can exclusively confirm. The couple is expecting their little bundle of joy in the spring.

"Brady is due [in April] and she is feeling great," a source reveals to Us. "They are not finding out the sex and are keeping the baby's gender a surprise."

Schwartzman, 33, and the fashion designer tied the knot in July 2009 and are already parents to daughter Marlowe, 2. "Marlowe is super excited about becoming a big sister and they are thrilled to be adding to the family," the insider adds to Us.

The parents are used to surprises. Schwartzman and Cunningham decided to not find out about Marlowe's gender, too. "We don't know the sex of our baby so that's going to be a great moment," Schwartzman previously told Us in September 2011.

He was also excited to show his first child around the couple's home at the time. "I read a book that said you're supposed to do that -- it's called The Baby Whisperer," he recalled. "You're supposed to take the baby around and be like, 'This is the bathroom. And this is the living room.'"
