"That is really exciting news to have Katherine now be pregnant and have a baby," he gushed. "I don't know when exactly, but sometime this summer. I'm really looking forward to playing around with whatever it is, she or he is, and have some fun. I think this is kind of a unique experience."
While he looks forward to having a grandchild to play with, Arnold has also been thinking about the famous gene pools the baby will be made up of.
"Think about this for a second... There's three gene pools that you can do. There's Kennedy, there's Schwarzenegger, and Pratt. We can do anything," he joked. "We can go and solve the Cuban missile crisis... We can go and train dinosaurs. I mean, think about it!"
"That is a lot of power here!" Arnold added. "We'll see if this kid ends up with an accent."
