"Beatrice Jean Howard-Gabel Born Jan 19 2012 8lbs 6oz Bryce & Baby B are spectacular Daddy Seth & brother Theo are beaming ear to ear :-)," the filmmaker tweeted Saturday evening.

Bryce Howard and her actor husband who appears on the series "Fringe" also have a 4-year-old son, Theo. Howard has spoken publicly in the past about her struggles with postpartum depression after his birth in 2007.

The most recent big-screen appearances for Howard, 30, were in "50/50" and as a member of the ensemble cast of "The Help." She also appeared in "The Twilight Saga: Eclipse." Her movie career began with uncredited bit parts in films by her director-producer father.

"Beatrice's arrival is hugely exciting for our family," Ron Howard tweeted. "Thanks for all the kind tweets folks."
