Goldberg and Dolph Ziggler were pulled apart as they attended a porn star's birthday party.
The two WWE superstars were guests of adult actress Kendra Lust at the Andiamo Italian Steakhouse in Las Vegas.
Goldberg, 52, was caught on camera as he confronted Ziggler at the exclusive bash.
Ziggler is believed to have been sat at a table with Lust, who is a close friend of Ziggler's partner and fellow WWE star Dana Brooke.
But the pair exchanged words and tensions nearly boiled over inside the restaurant.
Three-time world champion Goldberg shared the footage of the event on his own social media.
Onlookers can be seen watching on and filming the event from their tables.
Goldberg and Zigger were separated by other males in attendance, including UFC middleweight fighter Eryk Anders.
Writing on Instagram , Golderg said: “What happens in Vegas obviously doesn’t stay in Vegas.
“My usual stop came with an unexpected surprise, looks like Ziggler and I still don’t see eye-to-eye.
“Fortunately for him I wasn’t still hungry.”
Goldberg and Ziggler faced off against each other at WWE's summer pay-per-view event SummerSlam earlier this year.
In the match, Goldberg made light work of Ziggler.
It is unclear whether the new footage is part of a WWE feud, thus being staged, or it indeed was a clash of personalities away from the bright lights of the TV cameras.
Matt Riddle, a WWE NXT star, chimed into the confrontation on Twitter .
Riddle, who has been openly taunting Goldberg in recent months, said: “Why didn’t you try this with me. I would have had an even better story for Watch Along.”
Riddle had previously spoken about his feud with Goldberg on an episode of the WWE Network show Watch Along.
Goldberg's current status sees him 'semi-retired' and only competing on matches on special occasions.
He was inducted into the WWE Hall of Fame last year, following a glittering career which saw overwhelming success in the 90s and 00s.
