Justin Bieber and Victoria Justice Celebrate Christmas in Washington

Justin Bieber, Victoria Justice, and Jennifer Hudson performed for President Barack Obama and family at the annual “Christmas in Washington” on Sunday night.

The stars took to the stage at the National Building Museum for the annual holiday show to raise money for the Children’s National Medical Center. Obama and his family were the guests of honor at the event, which was hosted by Conan O’Brien, and the funny man couldn’t help but poke fun at Bieber before his performance.

He told the audience, “It’s especially exciting to be here during this joyous season, when we celebrate the arrival of a miracle child, worshipped by millions around the world. Of course I’m talking about Justin Bieber… My eight-year-old daughter loves him. Or at least that’s what I tell people when they ask why I’m carrying a lock of his hair in my pocket.”

Other performers at the show included The Band Perry and Cee Lo Green, as well as the United States Naval Academy Glee Club and the Washington Youth Choir.

The previous day, Victoria, Justin and others visited the patients at the Children’s National Medical Center. The concert will air on this Friday on TNT at 8pm.
