President Barack Obama and first lady Michelle Obama dance as singer Jennifer Hudson performs “Let’s Stay Together” during the Inaugural Ball at the Walter E. Washington Convention Center on January 21, 2013 in Washington, DC.

*Jennifer Hudson was given the honor of serenading President Obama and First Lady Michelle Obama three times – for three separate Inaugural Ball appearances in Washington D.C on Monday.

The 31-year-old “American Idol” vet sang Al Green’s “Let’s Stay Together” for the couple’s first dance of the night at the Commander in Chief’s Ball, which took place at the Convention Center. President Obama famously belted a line from the song during a fundraiser in Harlem last year.

The slimmed down Hudson looked stunning in a cowl neck black gown and sparkly platform high heels for her performance.

She accessorized with large diamond chandelier earrings, an oversized cocktail ring and several bejewelled bangles. Her hair was in tumbling curls.
