Leslie Moonves and Julie Chen

Big Brother host Julie Chen will no longer just babysit reality TV stars.

Chen announced on The Early Show that she and husband Leslie Moonves are expecting their first child. The baby is due October 4.

Never fear, Big Brother fans: Chen said the pregnancy will not keep her from her weekly hosting duties for the 11th cycle of the show, airing this summer.

Chen and Moonves, the CEO of CBS, were married in 2004. Moonves has three grown children from a previous marriage.
