WATCH: Emma Watson and Lin-Manuel Miranda Throw Down in Feminist Freestyle Rap

In celebration of International Women’s Day, actress and feminist spokesperson Emma Watson teamed up with the creator and star of the musical Hamilton, Lin-Manuel Miranda, for a rap about women's equality. Miranda is famous — in part — for his ability to rap, on the spot, about nearly anything. Watson, the U.N. Women’s Global Goodwill Ambassador, is not famous for beatboxing, but she made an admirable effort nonetheless.
