While on The Zoe Ball Breakfast Show, Margot recounted the story and explained that she didn’t like her babysitter and wanted to do something about it.

“We got a new babysitter and I wanted my old babysitter back, Talia, who was like 16. I thought she was so cool,” she explained. “We got this much older lady in, and I was just not happy about it. 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.’”

She continued, setting the scene: “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.”

“But it was worth the wait,” she said, confirming that the babysitter ran “screaming from the house.”
