The final show of Beyoncé's Formation Tour at MetLife Stadium in East Rutherford, NJ started out with a bang, as opening act DJ Khaled brought out a bevy of special guests including The L.O.X., Young M.A., T.I., and Mase; and even engineered a backstage reunion of the almost-was Jay Z/Ja Rule/DMX supergroup Murder Inc. But that proved to be just a warmup for the main event.

During Beyoncé's set, she brought out none other than Serena Williams for "Sorry." Serena, of course, appeared in the track's video.

As if that wasn't high-profile enough, Mrs. Carter brought out Mr. Carter towards the end of the night for "Drunk In Love":
