Beyonce to sing during Obama's first dance as president

Beyonce has revealed the song she plans to serenade the Obamas with in their first dance as first couple – the Etta James classic 'At Last'.

Beyonce portrayed the blues great in the recent film 'Cadillac Records' and sings the song in that movie.

The singer, who recently had a US No. 1 with 'Single Ladies', will sing at the official Neighbourhood Ball on Tuesday night.

The singer-actress said singing for the Obamas’ first dance is a dream come true.

In a statement, Beyonce said: “I am so honoured that I will be performing for President Obama and the first lady. To sing 'At Last' while they have their first dance is a dream come true. I could not be more honoured and excited that they have asked me to be part of this moment in history.”

A day after Obama’s victory, Beyonce giddily offered to do anything the Obamas needed at Tuesday’s inauguration during an interview. Beyonce, along with husband Jay-Z, were Obama supporters and went out to campaign for him during the election.
