Dressed for the occasion in an American flag-themed costume, Katy Perry took the stage at the Walter E. Washington Convention Center on Saturday night for the Kids' Inaugural: Our Children, Our Future.
First Daughters Sasha and Malia Obama had front-row seats to the show, which is dedicated to America's military families and streamed to military bases across the country. The event, hosted by Nick Canon, also featured Usher, Far East Movement, and members of the Glee cast.
Katy Perry closed out the night with "Firework," "Part of Me," "Wide Awake" and "Teenage Dream."
"I'm very proud to be here ... and to see the Obamas and the Bidens here for four more years," she said.
