Jon Voight spoke to OK! about his grandchildren, saying: "All the kids are smart, I tell you.
"They're beautiful children."
And it looks as though tomboy Shiloh is particularly bright...
"Shiloh - boy, she's a smart one... She's four years old but you can never tell what she knows to look at her face all the time" said the actor.
“But I like seeing them no matter where they are. I don't read the stuff; I just look at their picture and swoon. I love them."
