Clooney and Kimmel had been talking to young actor Daniel Ranieri about his role in the movie when Roberts made her blink and you missed it cameo.
“Oh my goodness, wow. Holy moly,” Kimmel said. “George, I don’t know if you’re aware of this, but there’s a woman sitting next to you.”
Clooney didn’t address the joke at all.
“Maybe I hallucinated that. It looked like Julia Roberts though,” Kimmel laughed.
Clooney and Roberts are together because they are currently filming “Ticket to Paradise.”
“The Tender Bar” hits theaters Dec. 18 and on Amazon Prime Video on Jan. 7.
