Neil Patrick Harris and David Burtka's daughter, Harper Grace, stole the show at the New York City premiere of Wicked: For Good. Harper, 15, attended the Monday, November 17, event with Burtka, 50, donning a green sequined gown in an homage to Cynthia Erivo's Elphaba. The teen accessorized her look with a black fur coat and simple black heels. Burtka, for his part, donned a silver metallic suit jacket, black slacks and a white button-down shirt, seemingly a stylish nod to the Tin Man.
