Beyoncé and Jay Z are on a concert tour together, did you know? They might be breaking up. This whole marriage thing might have been an elaborate business arrangement. There might be hidden messages in their Instagram photos. Anyway, you can continue to sift for clues in the latest trailer for their upcoming HBO concert special, On the Run. In it, Beyoncé sings "Bang Bang (My Baby Shot Me Down)" (more in the style of Nancy Sinatra than Cher) while wearing a sequined dress as a cigar-smoking Jay Z looks on. What does it mean?! Not much, probably.
