The x factor unshown audition?

[penlid]

At the end of a few episodes of the x factor (the bit that showed what is coming in the forthcoming weeks) it showed a girl interviewed after an audition and she says "the judges are obviously stupefied". I haven't seen this audition even though it has kept being advertised. Did i miss it or was it shosn? Thank you for any help =D

It was maybe shown on the Xtra factor.
