“Beatrice Jean Howard-Gabel Born Jan 19 2012 8lbs 6oz,” the Missing director tweeted of his daughter’s newborn on Saturday afternoon.

Already mom to 4-year-old son Theo Gabel, Ron explained that Bryce, 30, is doing well post-delivery and that the whole family is, “beaming ear to ear,” to welcome a girl.

“Bryce & Baby B are spectacular,” the 57-year-old Happy Days star added of his daughter and newborn grandchild, “Beatrice's arrival is hugely exciting for our family.”

But, what’s even more exciting is that acclaimed Sixth Sense director M. Night Shyamalan is already recruiting the 4-day-old for the big screen, which makes sense seeing as though she comes from a family of actors and directors!
