The 11-year-old singer, born in the UK to South African parents, will take part in the "Britain's Got Talent" final over the weekend.
Jezile's parents, Luyanda and Prudence, moved to England from the Eastern Cape over a decade ago.
Jezile is one of 12 performers who will take part in the finals of Simon Cowell’s ITV show on Saturday, where the winner will walk away with R3.8-million in prize money. The winner will be chosen by a public vote.

The London schoolgirl wowed the judges in the audition with a cover of Rihanna's Diamonds, but it was her version of Beyonce's Halo that won her a place in the final.
After the show, she said: “I chose to sing Halo because it is such a powerful song. I wanted to show the judges I am versatile."
Her parents have been supporting her every step of the way.
After she won her place in the final, her father told ITV: “I am so, so happy and proud of Asanda. There was really tough competition because there was a lot of talent. We had a little doubt that she would get though to the final because of that, but we always thought she could do it".
