The previous month, during the premiere of his new Netflix series Fubar, Arnold opened up about what it’s been like to watch his daughter become a mother.

“It's nice to see your kids having kids themselves and to watch this new dimension,” he told PEOPLE exclusively of Katherine. “You see them growing up and you see them going to school and getting smart and getting their degrees, getting their jobs and all this, but now seeing them be a parent? It's fantastic. It's really great.”

The Kindergarten Cop actor went on to talk about how much he enjoys spending time with Katherine and her daughters.

“I just love when she [Katherine] comes over to my house or when I go over there, but most of the time she comes to my house because I have all the animals," he said. "The grandchildren love the animals. I have a pig so now they want to come over there and feed the pig all the time, hang out with the little pig.”

“It's really fun to watch and hang out with her now and to see the way she'll react to the kids because she is so great with them,” Arnold added.
