For a few weeks the corner of the world that still cares about Janet Jackson has been asking one question – what’s wrong with the woman?

Janet Jackson has been cancelling swathes of concerts on her current Rock Witchu tour because of a mystery illness that suddenly took hold five minutes before a show in Canada. The fact alone that nobody would reveal the illness was a cause for consternation – but now we know.

Janet Jackson has been suffering from migraine-associated vertigo. We’re sure that Janet Jackson’s fans are all completely sympathetic to this diagnosis – don’t forget that symptoms of vertigo include nausea, vomiting and difficulty standing – all of which will be familiar to anyone who witnessed Janet Jackson pop a nork out during the Super Bowl halftime show of 2004.
