DeGeneres brought out Edgar Martirosyan, the owner of a Big Mama's and Papa's Pizza shop in Los Angeles, at the March (14) prizegiving to dish out hot snacks for hungry A-listers including Meryl Streep, Brad Pitt, Angelina Jolie and Jennifer Lawrence.
The talk show host, who served as host at the Oscars, has invited Martirosyan on to her show several times, but on Wednesday (07May14) she surprised him with a special guest - the Pretty Woman star.
DeGeneres told Roberts, "What a coincidence that we would get a guy from Russia who grew up watching Pretty Woman. You were his favorite movie star of all time and now he's serving pizza to you."
When DeGeneres brought Martirosyan out to deliver pizza to her audience, Roberts came out from hiding behind some potted plants on stage, walked up next to her superfan and said, "Do you have pizza in there?"
Matirosyan replied 'Yes' before realising it was his favourite movie star, and with mouth agape, he gave her an embrace.
