One pop star is pretty great. Two pop stars? Legendary! But a whole host of pop royalty singing and dancing in one video? You've got yourself a certified culture-shaking moment.

Taylor Swift's "Bad Blood" — her not-so-subtle 1989 Katy Perry shade attack — rocked the pop world upon its video debut in May, thanks to a enviable roster of bad ass besties, including her arch-nemesis Selena Gomez (playing a dark-haired vixen), Hailee Steinfeld, Paramore's Hayley Williams, Jessica Alba, Zendaya, Kendrick Lamar, Ellie Goulding, Gigi Hadid, Lena Dunham and Cara Delevigne.

One might have assumed that assembling an equally superstar roster would be an all-but-impossible feat, but just one month later, the Queen of Pop herself came in with a powerhouse visual of her own. Yesterday, Madonna debuted her cameo-filled clip for her noisy Rebel Heart self-celebration banger "Bitch I'm Madonna," and primarily thanks to the magic of green screen and camera phones, she was accompanied by a whole suite of pop legends, including Beyoncé, Kanye West, Miley Cyrus, Rita Ora, Alexander Wang, Jeremy Scott and, intriguingly, Katy Perry. (Hi, Taylor!)

The two clearly have no beef between each other — they only just performed together onstage at the 2015 iHeartRadio Music Awards, after all! But here's the question: Which ensemble visual towers above the other? Did Madge's Boom Boom Room romp prove to be the most fun? Or was Tay Tay's futuristic kick-ass showdown steal the spotlight?
