THE NEIGHBORHOOD BALL FEATURING BEYONCE AND PRESIDENT AND FIRST LADY OBAMA TAKING THEIR FIRST DANCE.

The Obamas were serenaded by Beyoncé during their first dance at the Neighborhood Ball Tuesday night.

Beyoncé sang Etta James' "At Last," from her role in the movie "Cadillac Records" as the couple laughed and took their first spin around the dance floor.

Before the dance, Obama addressed the crowd, which erupted in applause when he entered the room.

"First of all, how good-looking is my wife?" Obama joked.

All eyes certainly were on Michelle Obama, who had kept her choice of a designer and dress style a secret until literally the moment she entered the dance floor.

The first lady was clad in a long white gown designed by up-and-coming designer Jason Wu. His design style combines modern lifestyle dressing and haute couture, according to his Web site. This young man grew up in Vancouver, Canada.

That dress and that dance was fab! Beyonce asked for the job and she got it! I even predicted it at my music blog! Some of these are my screen shots.
