Michelle Obama at Children's Concert in Washington DC 2013

Michelle Obama got some serious pop star support when she hosted the Kids' Inaugural concert in Washington DC last night. Michelle was joined by her daughters, Malia and Sasha, and Second Lady Dr. Jill Biden as she thanked the military men and women in the audience for their service and introduced the night's performers, including Katy Perry and Usher. Katy gave a particularly patriotic performance, dressed in a star-spangled romper, while Usher chose an all-black ensemble. Other acts of the night included the cast of Glee and the Soul Children of Chicago. The Kids' Inaugural concert kicks off the 57th presidential inauguration, which takes place on Monday. Despite all the other glamorous balls and events, Michelle talked about how the Kids' Inaugural has become her favorite moment of the weekend. She told the crowd, "Inauguration is a really big deal. There're balls. Everybody dresses up and dances. Let me tell you: I love every single minute of it. Every single minute. But I have to tell you that my very favorite part of this entire weekend is being right here with all of you."
