I actually recognised her from previous years - she seems to be a permanent fixture at bootcamp, yet I don't think we've ever seen her perform. Pretty crappy to not even montage her.
Right enough, she's present in this video from 2011's bootcamp (at 2:30): https://www.youtube.com/watch?v=P4dprMoLWnQ
I have a feeling we might have seen more of her on Xtra Factor one of the years, but I can't for the life of me remember her name (or anything about her for that matter).
