Emilie Fleming's dreams of starring as Dorothy in The Wizard Of Oz were dashed when she was voted off Over The Rainbow.
The 19-year-old from Tyne and Wear became the fourth contestant to be eliminated from the BBC One talent show.
Emilie, the public's "wildcard" choice to become a finalist, found herself in the sing-off with fellow hopeful Sophie after the duo received the fewest viewers' votes.
The eight Dorothy finalists each performed a pop song live on Saturday night in front of the studio audience and expert panel.
Musical supremo Andrew Lloyd Webber opted to save Sophie after listening to the pair sing again in the results show, tackling I Know Him So Well from Chess.
On hearing the announcement Emilie said: "I've got to say I want to thank my mum and dad, I wouldn't be here without them. Thanks to the public for voting me in.
"I've had an amazing experience and learnt so much. I'm going to toughen up, and I'm going to train, and you'll see me on the stage. And to the girls, I love you all."
Before announcing who was in the bottom two, host Graham Norton asked each panel member who "wasn't Dorothy" and they were unanimous in choosing Emilie.
