Before taking home her first-ever Emmy, for Outstanding Variety Sketch Series for "Inside Amy Schumer," Amy chatted with "Extra's" Mario Lopez about the best night of her life... which involved Madonna! The comedian, sporting a strapless Zac Posen gown, recently opened for three of Madonna's Rebel Heart Tour shows in NYC, where she flashed her underwear, twerked, and received a spanking from the Queen of Pop herself.
