Margot Robbie was terrified she 'wasn't sexy enough' for Wolf of Wall Street role

Margot Robbie didn't think she was 'sexy enough' for her role in The Wolf of Wall Street.

Let's be honest - that is a bit ridiculous.

But it just shows that even the best-looking people still have their doubts.

The Australian actor famously starred in Martin Scorsese's 2013 Oscar-winning hit alongside Leonardo DiCaprio, who played former millionaire stockbroker Jordan Belfort.

Robbie starred as Naomi Lapaglia, a character inspired by Belfort's second wife Nadine Macaluso.

Although Robbie is considered to be one of the most beautiful women in the world, she was 'terrified' that people didn't think she matched the criteria of the film script.

In a 2017 interview with Wonderland, she said: "I was terrified that people would see the movie and think, 'Ugh! She's not good enough.'

"I was very conscious that the script said, 'The sexiest blonde ever'.

"Clearly I'm not the sexiest blonde in history."

Recalling one of the many crazy sex scenes in the movie, Robbie says real money is a lot softer than fake movie money - I mean how would we know?

In a 2017 interview with The Daily Beast, Robbie explained: "I got a million paper cuts on my back from all that money! It's not as glamorous as it sounds.

"If anyone is ever planning on having sex on top of a pile of cash: don't.

"Maybe real money is a bit softer, but the fake money is like paper, and when I got up off the bed, I turned around to get my robe and everyone gasped.

"I said, 'What is it?' And they said, 'you look like you've been whipped a million times. Your back is covered in a thousand red scratches'."

Back in 2015, Robbie also revealed an embarrassing moment on set when DiCaprio's e-cigarette accidentally got stuck in her bum after a sex scene.

She previously told The Talk that she was unsure if the Titanic actor wanted her to share the story.

Well, it's a bit late now.

"I don’t know if he wants me telling this story, but we’d just finished this scene and Leo always carries an e-cigarette with him, like all the time," she explained.

"So he hid it under a pillow while we were shooting. Afterwards … he’s like, ‘Where is it? Where did I put it? I had it right here.’

"I was looking around with him – both still sitting in this bed – and then I went, ‘Oh, um, it’s literally, like, in my butt crack. I’m sitting on it. I am so sorry.’

"He probably threw it away. It was so embarrassing. So yeah, sex scenes are super sexy."

The fact the e-cig somehow jumped from underneath his pillow to her butt crack is a bit strange, but there you go.
