Michelle Obama Shows Some Skin As Family Joins Justin Bieber, Jennifer Hudson And Conan O'Brien To Sing Carols

The Obamas got in the festive spirit by singing with musical stars Justin Bieber, Cee Lo Green, Jennifer Hudson, Victoria Justice and The Band Perry at the 30th annual Christmas In Washington concert tonight.

The President, wife Michelle, daughters Malia and Sasha and mother-in-law Marian Robinson attended the concert to benefit the Children's National Medical Center in the capital.

Michelle was seen showing off some skin when she had to bend to have a little chat with the children in elves. I didn't see anything.... Nice dress anyway!
