The wait for Katy Perry's video for "Swish Swish" is almost over. The artist shared a sneak peek of the newest Witness single's video on Aug. 21, and it's filled with enough surprises to last you for some time. Leave it to Perry to keep things pretty literal all of the time, too, as to go with the hook "swish swish, bish. Another one in the basket," the singer actually puts a competitive basketball game at the center of the upcoming video. But it won't just be Perry on the court — there are quite a few familiar faces getting down and dirty. And below is a list of every celebrity cameo in the "Swish Swish" video, as seen in the trailer.

With the game dubbed "the hottest mess in history," it looks like Perry really pulled out all of the stops to get an array of talent to participate. And it's a hilarious "hot mess," indeed. From Brooklyn Nine-Nine's Terry Crews to professional strongman and former basketball player Thor Björnsson, the VIPs come from far and wide to vie for what seems to be the winning title of an eccentric Olympic game. It's an all out war between Team Sheep and Team Tiger, and there's no telling who will take home the grand prize when these stars are involved.
