Margot Robbie once gave her babysitter quite a scare.

Speaking to BBC Radio 2, the Barbie star revealed she once faked her own death using a kitchen knife and some ketchup, all to get revenge on her babysitter.

"We got a new babysitter and I wanted my old babysitter back, Talia, who was like 16 and I thought she was so cool. And then we got this much older lady in and I was just not happy about it," the actress shared.

Robbie recalled a time when her new babysitter got "cranky" when Robbie refused to take a bath, which led the actress to fake her own death.

"I thought, 'I'm gonna show you,' and so I got a big kitchen knife and the ketchup and I sprawled out naked on the tiles, covered myself in ketchup and put the kitchen knife and I waited for like 45 minutes for her to find me," she shared.

The babysitter eventually discovered Robbie in the kitchen with what appeared to be blood, and she ran out the door screaming.

"It was worth the wait," Robbie joked.

The moment proved Robbie could certainly stage a scene, but it wasn't the only time the young, then-future star showed off her acting talent.

"I also once practiced, like, a pratfall on the cinema stairs at the shopping center where I'm from. People started calling an ambulance so, I guess I was a bit of a dramatic child," Robbie told BBC Radio 2.

Barbie is out Friday (July 21). Just don't take a pratfall on the way to the movie theater.
