The ambitious youngster is seen performing a take on John Legend classic Ordinary People on this evening's final show.
"I don't remember when I first started singing but I'm really passionate about it. I want to be like Elton John or Queen," the student explains beforehand. "I want to be someone people remember in 50 years time."
Before stepping out in front of the coaches (or at least their backs), Becky adds: "When I get on that stage I hope to God I just block everything out because I have a feel it's going to be incredible."
But will any of the coaches turn around?
Going into tonight's final show, Jessie J, Danny O'Donoghue and Sir Tom Jones need just two acts to complete their teams, while Will.i.am needs three.
Tune into The Voice UK at 7PM tonight on BBC One to see how Becky gets on!
