Susan Sarandon is expecting her first grandchild — but don’t call her Grandma!

With Kyle and Eva Amurri Martino expecting a babya girl! — the actress seems to have settled on a new name for herself.

“I borrowed this name from a very dear friend of mine who’s from the South, and his grandma was ‘Honey,'” Sarandon, 67, told PEOPLE at the Endometriosis Foundation of America‘s 6th Annual Blossom Ball in New York City Friday.

“That’s what I’m experimenting with, and Eva likes it, so we’ll see.”

Sarandon had to get creative when it came to settling on her new moniker.

“I think it’s good because this is [Kyle’s parents’] seventh grandchild, so they’ve established what his parents are called,” she says.

But despite daughter Amurri Martino’s wishes, Sarandon plans on spoiling the family’s newest addition — in fact, she’s already been busy shopping.

“[Both of their birthdays are] this month,” she explains. “So for her birthday and his birthday, they’re getting [a] little crib and changing table.”
