Susan Sarandon welcomes first grandchild Marlowe Mae

Susan Sarandon became a first-time grandmother over the weekend.
Eva Amurri Martino, the 67-year-old actress' daughter with Italian director Franco Amurri, welcomed her first child with husband Kyle Martino on Saturday. The baby weighed in at 6 lbs., 11 oz., and the couple named her Marlowe Mae.
A representative for the Martinos tells People the parents are "thrilled and enjoying the new addition to the their family."
The couple have been married since October 2011, and announced the pregnancy in February. Eva is a 29-year-old actress, while Kyle is a 33-year-old NBC Sports soccer analyst. The new mother took to Twitter on Monday to share the happy news about her daughter.
"What a weekend!" she wrote. "@kylemartino are thrilled to announce the arrival of our sweet baby girl! Mama and Daddy love you a zillion, Marlowe Mae."
Eva will next appear alongside her mother in Mothers Day in 2015. Susan told People in March she plans to be called "Honey" instead of "Grandma."
