There was a whole lotta fa-la-la-la-la-ing in Washington this weekend.

Justin Bieber, Jennifer Hudson, Cee Lo Green, the Band Perry and Victoria Justice all sang for the first family at the annual “Christmas in Washington” concert at the National Building Museum on Sunday. The televised concert airs on TNT this Friday at 8 p.m. Chris Richards has a behind-the-scenes-report right here.
