In this first promo clip, Jessie reveals her reasons for singing up to take part, explaining: "It's all in the title, there are many things you can do in this industry but the voice is the main thing for me, always has been and will be."
She continues: "I like the format and the idea, it's fresh and new and it's something everybody's going to watch."
The 23-year-old singer, the youngest member of the panel, added: "It's real, it's not about what you look like, the package or the story or how many people you brought to the audition or who whether you can do a back flip, it's about there and then and the moment."
The Voice UK launches on BBC One on March 24.
