Usher, Justin Bieber And Mary J. Blige To Help The President Celebrate Christmas

Wednesday night's "Christmas at Rockefeller" helped celebrate the Christmas season in New York with Aretha Franklin, Rob Thomas, Michael Bublé and Lady Gaga fan Barry Manilow. But the nation's capital has to celebrate yuletide cheer too, which is why "Christmas in Washington" will bring Usher, Mary J. Blige and Justin Bieber to the National Building Museum for a concert that is expected to be attended by Barack and Michelle Obama. The show tapes on December 13 and will air on TNT on December 20 at 8 p.m. The show won't just be about festivity and good music — it will also benefit the National Children's Medical Center.

Rounding out the eclectic lineup will be Rob Thomas, Neil Diamond and Sugarland, with the whole event hosted by comedian and late night host George Lopez. Though it seems likely that the performers will stick to holiday songs, though the show will air the day before Usher's Raymond vs. Raymond was supposed to drop in stores (it has since been bumped to "TBD"). Bieber is by far the most intriguing participant in this show, as he is certainly the least-established of all the performers but arguably the one with the biggest buzz surrounding him (save for his mentor Usher). Could this be the opportunity for another Usher/Bieber tag-team, just like they did on "Ellen" a few weeks ago? That sort of thing could make this year's version of the annual event truly memorable.
