Beyoncé and Jay-Z Attend Obama's Inauguration

Four years ago, Beyoncé performed “At Last” as Barack and Michelle Obama took their first dance as President and First Lady of the United States. On Martin Luther King, Jr. Day, the 31-year-old singer was invited back and asked to sing the National Anthem during the president’s second inauguration ceremony in Washington, D.C.

Prior to her patriotic performance, Bey and husband Jay-Z made an elegant entrance at the West Front of the U.S. Capitol. Hip-hop’s First Couple beamed with pride as they walked arm in arm in all black (Bey looked gorgeous in a floor-length Emilio Pucci gown, 80-carat emerald earrings, and a 50-carat emerald ring by Lorraine Schwartz).

They greeted the First Family and even asked someone to snap a photo of them on an iPhone while overlooking the National Mall.
