President-elect Barack Obama’s inauguration is looking to be a huge star-studded event. Beyoncé has been tapped to sing for Barack and Michelle’s first dance on inauguration night, according to the Associated Press. But the mystery remains as to what she’ll be singing. “It is our hope that we can keep the song secret until the moment,” Presidential Inaugural Committee spokeswoman Linda Douglass told the AP. Meanwhile, Beyoncé will be joining her husband, Jay-Z, Mary J. Blige, Stevie Wonder, Alicia Keys, Mariah Carey, Shakira, Sting, Faith Hill, will.i.am, and Maroon 5 for Tuesday night’s Neighborhood Ball, where Jessica Alba, Leonardo DiCaprio and Kate Walsh will be presenters.
