That was a real pizza delivery guy, not an actor, who helped Ellen DeGeneres pass out those pies to the Oscar audience.
The show host met him in a backstage hallway to check out the goods.
“Is it hot?” she asked him. He assured her it was.
“What kind we got here?” she asked. Cheese and veggie with no cheese, he told her.
“Ok. Let’s go!” She said, leading the delivery guy onto the Oscar stage.
