VIDEO : Katy Perry's Cameo-Filled Music Video For 'Swish Swish' Features Wacky Basketball Team

Katy Perry just dropped a music video for "Swish Swish."
Perry leads a bumbling basketball team consisting of Gaten Matarazzo ("Stranger Things"), Jenna Ushkowitz ("Glee"), viral video star Christine Sydelko, dancer Dexter Mayfield, and Russell Horning (Backpack Kid).
The other team is led by Hafþór Júlíus "Thor" Björnsson (the Mountain on "Game of Thrones).
A halftime show by Nicki Minaj helps inspire Perry's team, and they come back for a better second half.
