Susan Sarandon Daughter: Eva Amurri Martino Gives Birth To Second Child

Susan Sarandon is a grandma again! The 70-year-old actress announced on Twitter that her daughter, Eva Amurri Martino, gave birth to a baby boy on Wednesday.

Major James is the second child for Amurri Martino and her husband, Kyle. The couple already has a two-year-old daughter named Marlowe Mae.

The birth of Major is especially significant since he is the couple’s “rainbow baby,” a term given to infants born after a miscarriage. Amurri Martino revealed last year that she lost a baby at nine weeks pregnant. Eight months later, she announced she was expecting a baby boy.

Now that Major is here, the couple couldn’t be happier. On Thursday, the 31-year-old actress shared the first photo of her son and wrote, “Our hearts are bursting. Our family is complete. Thank you so much for all of your love and support.”
