“I gotta say that #LinManuelMiranda’s nerdom is the coolest thing to witness ever,” The Roots‘ bandleader Questlove captioned with his Instagram post. “It’s so disarming even @JLo was in her most playful mood she’s ever been in on our #FallonTonight set. Here I caught a moment of him fixing then #StylinProfilin her (my guess 15 foot) train of a gown. We performed #LoveMakeTheWorldGoRound benefiting our brothers and sisters caught up in the Orlando tragedy. Great moment 2nite. Hope you guys watch it.”
