Beyonce, who serenaded Barack and Michelle Obama through their first dance at the Neighborhood Ball four years ago, will sing the National Anthem at the president's inauguration Monday. Ahead of the momentous performance, Beyonce posted photos of her preparations on Instagram and Tumblr.
In one photo, Beyonce holds the "Star Spangled Banner's" sheet music. She also snapped a photo of the tape marks where the Obamas and Bidens are supposed to stand.
