Olivia Newton-John admits there's one scene in Grease she still doesn't understand.

It was the conspiracy sweeping the internet last week, and now the woman behind it has finally addressed the latest cinematic ~ zombie romance ~ theory.

Yes, we’re talking about the ‘Sandy was dead’ Grease fan theory.

Because 38 years after it was first released people still don’t understand that flying car scene at the end of Grease, the theory surfaced on some dark crevice of the world wide web.

It claimed the globally loved classic was not actually about an all-singing-all-dancing high school and two star-crossed lovers who came from opposite sides of the tracks at all, but rather a movie about a dead girl looking back on what her life could have been.

During her appearance on Tuesday night's episode of The Project, Sandy (a.k.a. Australia's own Olivia Newton-John) said she thought the rumours were hilarious.

"So hilarious that anyone would even conceive such an idea," she admitted before adding, "but I thought, 'If it's true, then we were the first zombie musical!'"

Wanting to know more about the film (let's be honest, who doesn't?) the panel asked Newton-John if the the film had been fun to make.

"Was it as fun to make as it looks?" panellist Peter Helliar asked.

"It was great fun and the energy was like that... It was a blast," Newton-John replied, saying that perhaps the funniest aspect of the film was their ages.

"We were all much older [than the characters]," she said.

"We were all in our late 20s being teenagers."

But when asked what the flying car scene was all about and what it meant in the grand scheme of the movie, it seems Newton-John's guess is as good as anyone's.

"I wondered what it was about but I didn't question it," she admitted.

"I thought it kept people interested. It's amazing to me that after all these years people are still talking about it. I think it's wonderful and funny... And who knows? Maybe that was the secret," she said finally.
