Getting in the holiday spirit yet? Some news to light up your Yuletide daze: A major roster of stars have just been unveiled to appear on TNT’s Christmas In Washington special, including Demi Lovato, PSY, Scotty McCreery, Diana Ross, Smash star Megan Hilty, and The Voice‘s Chris Mann.
Christmas in Washington will be hosted by Conan O’Brien for the second year; the show benefits the Children’s National Medical Center and will be attended by Barack Obama and Michelle Obama. (Swag, tho. Wonder if Beyonce and Jay-Z will make a cameo?) The show will be pre-taped on Sunday, December 9, but air on TNT on Friday, December 21 at 8p.m. ET (save the date!). Most notably, PSY will reportedly be closing the show with a very special “Gangnam Style” performance. Here’s all we’ll say on that: If the POTUS does the “Gangnam” dance, the Mayans were right.
