It will be the second child for the Veronica Mars actress, 33, and Parenthood actor, 39. In March of 2013, Bell gave birth to a baby girl, Lincoln Bell Shepard. Lincoln is now almost 16 months old.
"I can confirm that Kristen and Dax are expecting their second child and a sibling for Lincoln," a spokesperson for the couple told Entertainment Tonight. "The whole family is beyond excited."
After a four-year engagement, Bell and Shepard were married in October.
Bell can be seen in Showtime's House of Lies, which returns for Season 4 early next year. Shepard's Parenthood comes back for its sixth final season in September.
