Katy Perry set off some fireworks for members of the Navy, Marine Corps, and Coast Guard who are in New York City for Fleet Week by performing in concert at Brooklyn’s Pier 9 last night.

Dressed in her patriotic best, Perry wore an American flag dress for the occasion. Security was on high alert for the event, but how could it not be; there were hundreds of America’s finest in attendance. They were also the only people in attendance since they were not allowed to bring guests.

Sea men dock their vessels in the great city of NYC to experience the land from whence they came. I'm about to give them a show! #fleetweek—

Perry made the night even more memorable by recreating the iconic photo of a sailor kissing a nurse in Times Square at the end of WWII. She brought a member of our armed forces up on stage for the big kiss, reminding him of one thing:

“If you drop me I’m gonna sic all my friends on you!”

He didn’t. Perry and the Marine locked lips (Watch the video).
