On Wednesday night, Beyoncé kicked off her Formation tour in Miami. After obsessing over all the new pictures from Queen Bey's website — including one cute snap of Blue Ivy — it was time to wait for actual details about the show to trickle in. According to reports, Bey dedicated "Halo" to Jay Z, whom she called her "beautiful husband." She also invited two random fans on stage to perform "Single Ladies," and the results were absolutely shocking . . . in a good way.
