Actor Fabio was dining with friends when one stood to take photos close to a table Clooney was sharing with his girlfriend Sarah Larson.
According to In Touch Weekly magazine, Clooney thought the photographer was trying to take shots of him and asked her to stop--a request that annoyed his fellow diner.
The magazine reports Fabio went over to Clooney's table to explain, but the conversation became heated, and the long-haired actor was overheard telling the Michael Clayton star, "I thought you were a nice guy. Stop being a diva!"
The encounter prompted angry Clooney to stand up and approach Fabio.
An eyewitness tells In Touch, "The waiters broke it up before it got out of hand.
Clooney reportedly skipped the rest of his meal, asked for his bill and left.
Fabio's manager has refused to comment about the incident, but says, "George is lucky he didn't end up in the E.R."
