Margot Robbie held her head in absolute shame after forgetting what 'Barbie' means in Australia.

The award-winning star appeared in an interview alongside Barbie director, Greta Gerwig, to discuss the upcoming comedy flick set to hit our theatres next month.

It's clear the Barbie girl was definitely in her own Barbie world as her mind completely blanked when asked about the famed piece of Aussie slang.

Speaking on The Project, co-host Sam Taunton told Gerwig: "[Barbie] means so much to so many people. I'm not sure if Margot told you but the word barbie means something else in Australia."

Visibly baffled, the 32-year-old Queensland-born actress immediately asked: "What does it mean here?"

"Like a barbecue," he responded, leading Robbie, Gerwig and the other co-hosts to burst out in a chorus of laughter at the hilarious blunder.]

Gerwig can be heard joking: "Oh my god, we've lost her!"

"I'm so Barbie now I can't even..." the Babylon actor said. "A barbie, yeah, having a barbie."

"I'm blaming the jet lag by the way," she continued. "Don't blame the blonde hair, blame the jet lag."

The interview clip has since been shared to TikTok with dozens of viewers eager to weigh in on the ordeal.

One TikTok user explained: "'Shrimp on the barbie' is like one of the first stereotypes we think of with Aussies."

A second claimed: "She’s not Aussie anymore."

"Aussie citizenship revoked," echoed another.

A fourth joked: "The entire nation of Australia about to put Barbie on the barbie."

Others were seemingly more understanding with one writing: "She full high on Barbie haha.

Another explained: "Sometimes your brain re-associates words so after a year of hearing Barbie, she lost the context of having a barbie."

Makes sense.

"Nah it took me a sec too because I was thinking of the context of a person," sympathised a third while a fourth admitted: "It even took me a minute to realise that they were taking about a bbq. Easy mistake."

A fifth added: "Breh we call it barbie here in NZ as well and even I was like, 'what's a barbie?'"

Another revealed: "The way he worded that confused me too."

"This is kind of annoying because there’s no context… the word 'Barbie' does mean barbie doll to me, while 'having a barbie' adds the Aussie context," pointed out out a final TikTok user.

Barbie is set to be released in theatres later next month (21 July).
