Is it a new album announcement? Is it something to do with her make-up line? Is it a bum? Or boobs?

Nobody can quite make out what Rihanna's latest tweet is about, as the pop star simply posted a photo of two televisions - one with a static screen, one with a difficult-to-make-out image on its screen - with the caption 'Didn't they tell u?'
