Mariah Carey’s already celebrated Christmas in Rockefeller Plaza and tonight she’ll be saying “Merry Christmas To You” on ABC with help from her mom Patricia, but that’s not enough for the “Oh Santa” diva. The mother-to-be also helped deck the halls of our nation’s capitol for the television special “Christmas In Washington“. The Merry Christmas II You songbird was joined by Annie Lennox, recent Idolator interviewee Maxwell, Glee‘s Matthew Morrison and the Obamas at the National Building Museum. Ellen DeGeneres also made an appearance, though it seems she was only there for the chance to feel MiMi’s pregnant belly.
