Jessie J has posted a fairly excruciating piece of 'video content' on YouTube.
Opening with a short preamble about how "epic" her fans are for getting new single 'Domino' to Number One in the UK (it's currently the most downloaded song on iTunes), she then launches into a live version of said single.
There are also a few 'cameos' in the video and a bit where everyone clicks their fingers around Jessie's face.
It's 'quite something'.
