Katy Perry Kids Inaugural Concert Video: Watch Katy Perry Perform at Inauguration 2013

Katy Perry, a fervent Obama supporter who campaigned on behalf of the president during the 2012 election, and even wore several Obama/Biden-inspired outfits, was the main act at Saturday's Kids Inauguration Concert in Washington — where First Lady Michelle Obama and Second Lady Jill Biden hosted and entertained the children of military personnel. 

The activity kicked off the Inauguration 2013 festivities as Perry, one of the year's biggest teen idols (sorry Biebz) had First Daughters Sasha and Malia Obama — as well as the rest of the kids in attendance singing and dancing to her most popular hits. Watch the videos below:
