The new baby girl’s step-grandmother is icon Barbra Streisand. The Funny Girl star, 76, has been married to fellow actor James Brolin, 78, since 1998.

“My wife got her a bracelet that said ‘Grandma’ on it and she started crying,” the Sicario: Day of the Soldado actor said. “She is one of those … it’s annoying but in a really great way, [with] emails every day and like, ‘Hey, I thought of this name, what do you think of that? … When can I come over and feel the baby?’ “
