File this under Things You Never Thought Emma Watson [1] Would Do. When the actress-turned-feminist-advocate sat down with Hamilton creator Lin-Manuel Miranda [2] to talk about her women's rights campaign, HeForShe [3], things took an unexpected turn. Miranda, a bona fide lyrical genius who turned historical hip-hop into a worldwide phenomenon, agreed to freestyle rap about gender equality under one condition: that Watson throw down a sick beat.

What follows is hilarious and downright adorable — trust us and give it a watch for yourself. (And never, ever forget this image of Emma Watson attempting to beatbox like a pro! Where can we pick up her mixtape?)
