Inside the Obamas' Easter Egg Roll

The President and First Family welcome kids to the South Lawn of the White House for a day of play


Pop star Fergie serenaded the crowd – including First Daughters Sasha and Malia Obama – with her hit songs "Big Girls Don't Cry" and "Glamorous," as well as the national anthem. "It was a special moment in time as I got to see Michelle, Malia and Sasha dancing and singing with me to my songs," the singer told PEOPLE of the egg roll performance.
