Mariah Carey: Christmas in Washington!

Mariah Carey belts it out as she performs during TNT’s Christmas in Washington special at the National Building Museum on Sunday (December 12) in Washington, D.C.

The 40-year-old legendary singer was just one of many performers at the show – Miranda Cosgrove, Matthew Morrison, and Andrea Bocelli all performed! Ellen DeGeneres was also on hand for the special, which airs on Friday, December 17 at 8/7c on TNT.

Also pictured inside is the entire Obama family – love how excited Malia got during the show!
