Margot Robbie says she once faked her death to prank her babysitter by covering herself in ketchup: 'I waited 45 minutes for her to find me'

• "Barbie" star Margot Robbie pranked a babysitter she didn't like by faking her death.
• The Australian actor said she covered herself in ketchup and left a big kitchen knife on the floor.
• Robbie said she lay naked on the tiles and "waited 45 minutes for her to find me."

Margot Robbie has taken Hollywood by storm since she first caught attention in Martin Scorsese's "The Wolf of Wall Street" in 2013, gaining other huge roles like Harley Quinn in the DC Extended Universe, and Tonya Harding in "I, Tonya." Obviously, she's also leading Greta Gerwig's "Barbie" movie alongside Ryan Gosling.

But the star has seemingly had a flair for the dramatic since she was a child, as she recently recalled faking her death to scare a babysitter. 

Robbie made the admission on "The Zoe Ball Breakfast Show" for BBC Radio 2 in an interview to promote "Barbie."

"We got a new babysitter and I wanted my old babysitter back, Talia, who was like 16 and I thought she was so cool," Robbie recalled. "We got this much older lady in and I was just not happy about it, and she told me to go have a bath and I didn't want to and she was very cranky and I thought, 'I'm going to show you.'"

The future star hatched a plan to scare the older woman, involving ketchup and a kitchen knife.

"So I got a big kitchen knife and the ketchup and I sprawled out naked on the tiles, covered myself in ketchup, put the kitchen knife, and I waited like 45 minutes for her to find me," said Robbie.

Clearly, the actor has been committed to giving a performance for quite some time.

Asked if the sitter "ran screaming from the house," Robbie said: "But it was worth the wait… Oh, yeah."

Gosling, who was also in the interview, joked that Robbie "produced her own death."

Robbie also recalled another incident when she fooled people into thinking she was hurt.

"I also once practiced like a pratfall on the cinema stairs at the shopping center where I'm from and people called an ambulance. So I guess I was a bit of a dramatic child," said Robbie.
