Katy’s performance at the Macy’s Fourth of July Fireworks Spectacular was nothing short of great! Fans were treated to Katy singing “Part of Me” and “Firework”, the perfect song for celebrating Independence Day. The Navy servicemen and servicewomen in the crowd were pumped to see Katy Perry perform her songs at the Brooklyn Navy Yard in New York City. What a way to cap off a great July 4th!
