Mariah Carey Performed For 'Christmas In Washington.'

Christmas certainly came early in Washington as Mariah Carey was on hand to perform the popular Christmas song ‘O Come All Ye Faithful.’ She also performed ‘One Child’ which is pretty ironic seeing as though she will be having two children. Carey and husband Nick Cannon recently revealed that they are expecting twins.

The show, Christmas In Washington, was taped at the National Building in Washington, D.C. over the weekend, aired on Friday (December 17) and featured the pregnant singer belting out her favorite holiday tunes.

President Obama, First Lady Michelle and their two daughters, Malia and Sasha, attended the annual concert.
