R&B star Beyonce will sing as “First Couple” Barack and Michelle Obama share their first dance on inauguration night, according to The Associated Press.

Although what song the charttopping diva will perform for the historic affair remains a mystery. The Presidential Inaugural Committee hopes to keep the song selection secret until the big night.

Linda Douglas, a spokeswoman for the Committee tells The AP: “It is our hope that we can keep the song secret until the moment.”
