During her time on 'The X Factor' nearly a year and a half ago, Diana Vickers stood out from the other contestants due to her quirky style. But as she prepares to launch her pop career, the 18-year-old has ditched her teenage style for a sexier side.

Reality star to pop star: Diana Vickers reclines on a couch in nothing but a white shirt in the new video for her debut single 'Once'. The single comes from new album Songs From 'The Tainted Cherry Tree', which features a track 'Remake Me & You', co-written by Ellie Goulding, and other tracks written with Cathy Dennis.

Vickers signed a record deal last year, but was given permission to put recording her album on hold so she could star in the West End production of 'Little Voice', for which she received rave reviews.

During her time on the X Factor, Vickers stood apart from the other candidates for her insistence on performing in bare feet and 'The Claw', the nickname for her bizarre hand movements while singing. Still barefoot: Vickers's refusal to wear shoes on 'The X Factor' appears to have followed her to her pop career.

In a recent interview, she promised fans she would try to tone down her 'claw'. She said, "The claw - oh God. I don't even know why I do it, I have no idea. I literally just go free when I'm singing and I do really weird things. I haven't even sung live for ages as me, as Diana, so there might be some new movements popping up somewhere. I don't know, we'll see."
