"Video coming soon! Just tryin to make it perfect for all of you," Madonna Instagrammed. "We are hard werking bitches! #bitchimmadonna."
Madonna also posted a snippet from her video -- to be released today -- but it doesn't feature any of the female artists.
Last month, Swift dropped her "Bad Blood" music video, which featured a slew of her famous friends including Selena Gomez, Zendaya, Karlie Kloss, Mariska Hargitay and Ellen Pompeo ...to name a few. The song is thought to be about Perry.
