While everyone is getting judged walking down the red carpet, there's an un-televised pre-show for all the celebs that have already made it inside alive. Candid video shows an appearance by the more-talented-than-you-even-knew kids from Stranger Things, doing a surprise performance of Bruno Mars' Uptown Funk.

If you think performing at the Emmys is hard, imagine doing it for a bunch of nervous celebrities who don't know they're being filmed.

OMG!!! watch this!!! #strangerthings performs #uptownfunk before the #Emmys!!! @enews
