Aged 16 Jackie Green became the youngest person in the world to undergo transgender surgery.
Now as a 19-year-old woman, Jackie has made history once again by becoming the first transgender Miss England finalist, and a BBC3 documentary to be aired tonight follows the teen's mission to become a beauty queen.
Today the willowy brunette appeared on This Morning to talk about her life now as a wannabe model and the long road there, starting with a trip to America aged 12 to pause the onset of puberty.
Jackie, who was born Jack and spent her childhood trying to persuade her parents she had been born in to the wrong body, said: ''I knew from the start that I was a girl, it was just actually having the vocabulary to make people understand.
'I would have had the surgery at five years old if I could. After the surgery it felt like starting life for the first time.
'Loads of kids go through stages, some people go down the transgender route and then change their minds, mostly because they don't have the support of their family.
'At primary school I dressed as a boy for the majority of the time. The kids understood and just took it in their stride.
'But secondary school was horrible. I was being spat on, being beaten up and called so many different names. The parents were the worst.
'I was prescribed 'blockers' by a doctor in Boston when was I was twelve. It basically paused puberty and it saved my life.
'I would have killed myself. I wouldn't have been able to cope.
