Jessie has been on the show for several months, using the platform to showcase some of her own tracks including 'Domino'.

Jessie won the competition after performing her own cover of Whitney Houston's 'I Will Always Love You', originally written and performed by Dolly Parton.

Following her victory, Jessie took to Instagram to thank her fans. She wrote, "I will always love you is the song that made me want to be a singer when I was 4 years old. I have wanted to sing this song for YEARS. Trust me, but I only ever wanted to sing it if and when I felt I had earned it and deserved it. Singing Whitney is an honour. She is the BEST to ever do it. This moment was LIVE on TV in China and just before I went on someone said “A billion people are watching tonight”. I fought back tears / jetlag / my voice legit going to sleep before I could lol and sang as BEST I could. I wanted to make the four year old me / Whitney / my Mum and Dad / my team and all my heartbeats around the world proud. I cried like a baby after the last note ??❤️ Thank you China for giving me this moment. ????"
