Appropriately dressed (or maybe inappropriately, given the audience) in a tight red, white and blue outfit, Katy Perry rocked the 2013 Kids' Inaugural Concert Saturday.
"I'm very proud to be here and to see the Obamas and the Bidens here for four more years," Perry said during her star-spangled performance in D.C.
First Lady Michelle Obama and daughters Sasha and Malia were dancing and throwing their hands up as the pop star sang in honor of America's military families.
Those families, Michelle noted, are who this nation is all about.
"Now, inauguration is a pretty big deal," said the First Lady. "But I have to tell you that my very favorite part of this entire weekend is being right here with all of you."
