The Moneyball star, who has six kids with partner Angelina Jolie, said that he often offers them the caffeinated drink when they are slow to get ready on school days.
"I admit there's times like, 'We gotta get up. Get up!" Pitt revealed during an appearance on Inside the Actors Studio.
"'Here's your shoes. Here's your shoes. Drink this Coke. Drink this Coca-Cola. Drink it all. Right now! Drink it! Drink it! Drink it!' Just so we could get 'em up and going."
Pitt recently insisted that he won't marry Jolie until there is marriage equality despite how much it means to their kids.
He recently told a German newspaper that he and Jolie's children are banned from looking up the couple on Google.
