The "Fences" star, who has twins Olivia and Malcolm, 25, as well as John, 32, and Katia, 29, with his wife Pauletta Washington, said he is thrilled to hear the couple are expecting twins, reported Entertainment Tonight.
"Sleep now! Because you won't be sleeping then! Sleep now! I'm not talking to George, I'm talking to his wife. Sleep now!
"He's gonna need support, and not from an actor. It's going to be a real performance. He'll see, but it's beautiful. We have twins and they're grown now, but it's a miracle," Washington said.
