Born in the Isle of Man to Alan and Marguerita Jackson, she has an elder sister Alicia. The family returned to their parents’ home of Woolton, Liverpool, two years later so that her father could continue in his media career, where he is BBC Radio Merseyside’s sports presenter. Jackson attended St. Edward’s College, gaining 10 GCSEs, and then went on to Sixth form to study English Language, English Literature and Philosophy and Ethics.
