Jennifer Hudson Sings ‘Let’s Stay Together’ for Obamas’ First Dance at Commander-in-Chief Ball

Jennifer Hudson's powerhouse vocals provided the soundtrack to Barack and Michelle Obama's first dance of the President's second term. While Al Green's original 'Let's Stay Together' is a smooth, light, frothy soul classic, Hudson's strong bellow gave it a new feel.

Showing off her newly svelte figure in a black halter dress, Hudson was the sound -- but the Obamas were quite the sight and stole the show. Michelle rocked a red velvet gown while Barack donned a snazzy white bow tie with his tux. How cute are they -- and dude, how well can they move?
