Margot Robbie has confessed to a cruel prank she pulled on a babysitter as a child, which resulted in her faking her own death. The Barbie star admitted being disgruntled about the prospect of getting a new babysitter, and decided to get her own back. "I wanted my old babysitter back, Talia, who was like sixteen and I thought she was so cool", she told the BBC. She then admits: "I got a big kitchen knife and the ketchup and I lay sprawled out naked on the tiles, covered myself in ketchup and put the kitchen knife there." The babysitter reportedly ran out of the house screaming. We don't blame her. Sign up to our new free Indy100 weekly newsletter
