At Sunday’s Golden Globes, Sylvester Stallone was left fuming after he and his wife, Jennifer Flavin, were forced to leave their table because of a seating mix-up.

As the show started, Stallone and Flavin walked up to their assigned table – where “Manchester by the Sea” star Casey Affleck was seated, along with the film’s writer-director Kenneth Lonergan and producer Matt Damon – only to find that there was just one seat available.

Stallone, who won a Globe last year for reprising the role of Rocky Balboa in “Creed” and appeared as a presenter this year, retreated backstage to watch the ceremony with his wife.

A Globes insider told us, “Stallone and his wife came to the table late … and when they got there, there was only one seat available. It was a mix-up by the organizers … Stallone immediately went backstage to watch as Jimmy Fallon started his opening. But when the first break came, a production worker for the show brought out an extra chair to make room for Stallone and his wife. They had the best two seats facing the stage.”

But Stallone chose not to come back out to the table. We’re told Affleck was mortified about the Stallone seating snafu and tried to smooth things over backstage, only to be basically told by the “Rocky” legend, “Get out of my face!”

Stallone and Flavin’s three daughters Scarlet, Sistine and Sophia shared the title of Miss Golden Globe at this year’s show.
