Beyoncé is finally getting on with it.
She (or a social media intern) has just published a YouTube video containing about two seconds of quite good sounding music, along with text that suggests something big is happening TOMORROW AT 9AM EDT (2pm on proper time).
Be warned, there is a hashtag.
UPDATE: It looks like this is all a 'tease' for a new Pepsi advert. SERIOUSLY, WELL DONE EVERYONE.
