Perry, in partnership with DanceOn, launched the #SwishSwishChallenge, and is asking hopefuls to show off their moves in a video and post it online.
Perry announced the challenge in a YouTube video on Wednesday,explaining, "All you have to do is put together some fun, funny, weird, great choreography… and I will pick my favorite dancer to be in the music video with me!"
Those who want to participate have to showcase their talent by dancing to the catchy single -- which features Nicki Minaj and is off Perry's latest album, Witness -- and then share the auditions to YouTube, Instagram or Musical.ly, and tag them with "#SwishSwishChallenge" and the @DanceOn and @KatyPerry handles.
Submissions for the contest, open to dancers over the age of 13 who live in the United States, close on July 12 at 11:59 p.m., and the music video is set to film later this month.
While many have speculated that "Swish Swish" was written as a diss track aimed at Taylor Swift, Perry recently admitted to wanting to put their feud behind them, and ended up changing some key lyrics during an outdoor concert for her fans last month.
