Stars attended the taping of Christmas in Washington 2010 at the National Building Museum on Sunday (Dec 12).
Mariah Carey, who is pregnant with Nick Cannon‘s child, was there to serenade the Presidential family and guests of the event with some Holiday songs accompanied by a choir. The show was hosted by funny gal Ellen DeGeneres, who is seen standing next to Mariah sharing laughs and seemingly going in to touch her growing belly. A rub for luck?
Christmas in Washington will air on TNT on December 17th. More pics of Mariah below!
