Vince, who will be seen auditioning solo for The Voice UK this weekend, was eliminated in the third live final in 2007.
Vince - real name Matthew Protheroe - had auditioned for The X Factor solo, but was put into a group alongside Aaron Delahunty, Adam Chandler, Richard Wilkinson and Sean Rumsey.
They were mentored by X Factor and Britain’s Got Talent boss Simon Cowell, and went on to take part in the X Factor live tour of 2008.
