On March 21, Siwa teased the YouTube video, revealing to fans that Kardashian would make a cameo as well.

On Saturday, Siwa previewed the YouTube video on Instagram, sharing a picture posing with Kardashian and North. She captioned the photo, "You guys are not ready for this video! TOMORROW 12:00 PST!
