President Barack Obama and First Lady Michelle Obama shared a special first dance to Jennifer Hudson singing "Let's Stay Together" at The Inaugural Ball held at the Walter E. Washington Convention Center in Washington DC last night. Michelle wore a glamorous red Jason Wu gown for the occasion, which came after the official swearing-in ceremony and parade earlier today. Beyoncé Knowles performed the national anthem at that event, but this evening Alicia Keys, Brad Paisley, and Stevie Wonder took the stage to sing. It's been a busy few days in our nation's capitol with plenty of celebrities attending inaugural festivities over the weekend and even more famous faces stepping out tonight.
