Turns out it looks like a black square on Instagram because Harry, jokester that he is, posted the pic to show what taking a selfie when you wake up in the dark looks like.
He totally tricked us (admittedly, for a mini-second, we thought maybe something was wrong with the pic...duh.). We might have scampered over to Instagram as quickly as possible, expecting a half-naked Harry, hair messy, gazing up from his pillow. We were majorly disappointed.
But well played, Harry. You big tease.
