She sings, she dances, she acts, she has a new skincare line. But does she kill in a comedy club? Madonna added another notch to her creative belt on Tuesday night (Sept. 26) when she took the stage alongside pal Amy Schumer at New York’s legendary Comedy Cellar. The singer posted several pics from the surprise set, including one in which she’s standing next to Schumer, writing “And the next minute i was tagging along with @amyschumer at @nycomedycellar Making my stand up debut! What a thrill. Finally busted my cherry thank you Amy!”
