Rihanna‘s Navy and Beyonce‘s Beyhive are at war with each other, and it’s rather frightening.

The whole thing started when Rihanna favorited (and then un-favorited) a tweet that seemed to throw shade at Beyonce’s Super Bowl 50 performance of “Formation.”

The tweet read: “The fact that ’Desperado’ is HIGHER on the Bubbling under chart than a single performed to a global audience.”
