One of Beyoncé's dreams is about to come true: She will serenade Michelle and Barack Obama during their official first dance on Tuesday at the Neighborhood Ball in Washington, D.C.
"I am so honored that I will be performing for President Obama and the first lady," the singer tells Entertainment Tonight
. "I could not be more honored and excited that they have asked me to be part of this moment in history."
Beyoncé, who stars as Etta James in Cadillac Records,
will sing James's classic tune "At Last."
"To sing 'At Last' while they have their first dance is a dream come true," adds Beyoncé.
