Next month, Katy Perry will embark on her “Witness Tour”, joined by the likes of Carly Rae Jepsen, Purity Ring, and Noah Cyrus. Ahead of the jaunt, the pop singer has shared a wacky new music video for the album latest single, “Swish Swish”.

Helmed by veteran director Dave Meyers (Outkast, Missy Elliott), the star-studded, meme-tastic clip sees Perry shooting hoops in an oddball basketball game that looks like a hybrid of the Harlem Globetrotters and Space Jam. Molly Shannon and Terry Crews make cameos, as does Gaten Matarazzo from Stranger Things and “The Mountain” from Game of Thrones. Also appearing are popular vlogger Christine Sydelko, Minnesota Timberwolves star Anthony Towns and New England Patriots’ Rob Gronkowski. The song’s collaborator, Nicki Minaj, drops in for a hot halftime performance. Watch it up above.
