"I feel like if you went to lunch with Natalie Portman, she would only order a hot tea with lemon and maybe some toast. Definitely not an entree, though," the actress read.

"Oh, look at me, I'm Ryan Gosling, I have perfect bone structure and kind eyes. Go [bleep] yourself, Ryan Gosling," the actor read.

Stone read that she "looks like a crack whore in every role she plays."

"Great," she said.

Jackson read that he "has resting fart face."

"Yes, I do," he said.

"Robert De Niro is too old to be making gangster movies still. Due needs to start playing grandfather roles or something," the actor read. "Yeah, I am playing grandfather roles and pretty soon I'll be playing great-grandfather roles. [Bleep] you."

"Who knew Robert de Niro had such a potty mouth. That is shocking to me," Kimmel joked.
