Stephen Baldwin Details Bond With Hailey Bieber’s “Plump Potato” Baby

All of the family is feeling the baby, baby, baby fever.

Four months after Hailey Bieber and Justin Bieber welcomed son Jack Blues Bieber, her father Stephen Baldwin shared insight into life as a grandfather.

“We’re getting ready for Christmas with baby Jack Blues,” the actor told TooFab in an interview published Dec. 16. “We’re excited. And he’s grown like a weed. Actually, he looks like a little plump potato. He’s so cute. I can’t stand it.”

And thanks to daughter Alaia Baldwin’s 4-year-old daughter Iris, the 58-year-old already has a moniker for his grandkids to call him.

“We’re going with Grampy, but it’s with a W. A lot of people don’t know that,” he explained. “G-W-A-M-P-Y. That’s kind of the handle I’ve been going with. It was my granddaughter Iris, it was the name she gave me.”

And while Stephen—who shares Hailey and Alaia with wife Kennya Baldwin—admitted he wanted “to say so much,” he refrained from spilling more. After all, Hailey and Justin are keeping parenthood close to their chest.
