This is the first child for Martinez and the second for Berry, who has a five year-old daughter with model, Gabriel Aubrey.
Berry and Martinez tied the knot in July in France, and even in the midst of pregnancy, Berry did not slow down one bit.
She lobbied and succeeded in being part of a group that fought to finally get a Paparazzi law passed.
Berry plays a female astronaut trying to reconnect with her family when she returns after a year in outer space.
The series will air on CBS in the Summer of 2014.
"Halle is the type of award-winning actress you dream of collaborating with for an event project such as Extant," said CBS Entertainment president Nina Tassler.
