Jennifer Hudson, Justin Bieber, Cee-Lo Green, Conan O’Brien Celebrate Christmas in Washington with the Obama Family [PHOTOS]

The Obamas were joined by a host of celebs — including Jennifer Hudson, Justin Bieber, Cee-Lo Green, Conan O’Brien, Nickelodeon star Victoria Justice and The Band Perry — as they all got into the festive spirit Sunday (Dec 11) in Washington D.C. at the annual Christmas in Washington ceremony.

“This is the season to celebrate the story of how, more than two thousand years ago, a child was born to two faithful travelers who could find rest only in a stable, among cattle and sheep,” President Barack Obama, who was accompanied by First Lady Michelle and the First Daughters Sasha and Malia, said near the close of the concert, which was hosted by Conan O’Brien.

“He was no ordinary child,” Obama said. “He was the manifestation of God’s love. And every year we celebrate His birth because the story of Jesus Christ changed the world.”

Singers Jennifer Hudson, Justin Bieber, Cee-Lo Green, Conan O’Brien and Victoria Justice took turns singing classic holiday tunes like “This Christmas,” “Santa Claus is Coming to Town,” “Let It Snow,” “Do You Hear What I Hear,” “Away In a Manger,” “Silent Night” and several others during the concert, which is set to air on TV this Friday (Dec 16) on TNT.
