A mere two days after his sister Leslie was found dead at 25, a brave Nick Carter took the stage before 700 fans at New York's Irving Plaza Thursday, and RadarOnline.com has video of his performance.

The singer took time out to pay homage to his late sibling: "I never thought I'd have to, but I'd like to dedicate this song to my sister," Nick, dressed in a spaceman suit, said somberly before launching into the ballad Falling Down.
