Gearing up for an important performance, Beyonce Knowles was seen leaving her hotel in Washington, DC on Wednesday evening (May 19). The "Irreplaceable" singer happened to be heading to the White House to take part in President Barack Obama's second State Dinner.
Held in honor of Mexico's President Felipe Calderon and first lady Margarita Zavala, Beyonce will take the stage along with Mexican duo Rodrigo y Gabriela and the United States Marine Band. Drawing plenty of star power, other attendees include "Desparate Housewives" actress Eva Longoria, the lovely Salma Hayek, and talk show hosts Oprah Winfrey and George Lopez.
