The 22-year-old model-and-actress said she has never liked following rules and always "rebels" against things she does not like, reported Contactmusic.
"I don't like boundaries. If someone makes a boundary I don't like I'm a rebel ... I loved setting off fire alarms a lot at school. Just leaving horrible things in people's shoes, such as eggs.
"Once I left a scorpion in my sister Poppy's shoe. She didn't get stung, she saw it first. We had a horrible fight after though. I wasn't someone who got caught at school, ever. I was very much a ninja. Someone else would always get caught," she said.
