Rae Sremmurd's "Black Beatles" is now a top 10 hit because it features heavily in the viral videos making up the #MannequinChallenge. This morning, Paul McCartney posted his version of the challenge on Twitter. The former member of The Beatles was filmed standing next to his piano, his face pointed to the ceiling, looking very much like a mannequin. The clip was captioned with an approving nod to Swae Lee and Slim Jxmmi: "Love those Black Beatles," it read. Watch above, and check out Rae Sremmurd's version of the #MannequinChallenge here.
