Diana Vickers has been concentrating on her theatre career since she appeared on The X Factor back in 2008 and was voted out in the semi-final. She's now ready to release her music, and the video for her debut single "Once" has just come out. It's released on 19 April, ahead of her debut album Songs From The Tainted Cherry Tree which will follow on 3 May. If seeing Diana again has got you nostalgic for The X Factor, play my faceoff game all about who's the better singer! Check out Diana's video and vote to let me know: will you spin it or sling it?
