Happy Inauguration Day! We're totally psyched to Barack the next four years.

The inauguration certainly was kicked off right yesterday at the invitation-only Kids' Inaugural Concert with Miley Cyrus, Demi Lovato, and the Jonas Brothers. Malia and Sasha Obama went nuts when the JoBros took the stage and sang along to Demi's tunes. They even got a song, called "The Climb" dedicated to them by Ms. Miley! "You girls must be awfully proud of your dad -- and so am I," Miley said. What a way to kick off their career at First Daughters!
