Kicking off the "Good Morning America" Summer Concert Series, Lady Gaga performed songs from her hit album "Born This Way" in NYC's Central Park. For her "Edge of Glory" performance, Gaga began in an all-black ensemble, wearing a black masquerade mask and black lace veil. Gaga shedded the veil to reveal a patent-leather, glossy jacket with her signature shoulder spikes. (ABC News)
