Justin Bieber Joins First Family & Slew of Stars for Christmas Concert (PHOTOS)

Washington D.C.’s Christmas In Washington 2011 event held at the National Building Museum looked more like a Hollywood soiree Sunday night when the celebs hit the stage alongside President Barack Obama, First Lady Michelle and daughters Malia and Sasha. 

Everyone from Justin Bieber to Victoria Justice to Cee Lo Green to The Band Perry to Jennifer Hudson performed at the festive event, as the First Family looked on. Sasha even got a hug from teen heartthrob the Biebs when the family came up on stage. Of course, Justin, 17, sang his hit “Mistletoe.” Even funnyman Conan O’Brien was there to play host of the holiday gathering. 

Jennifer sang “Do You Hear What I Hear,” and said of performing for the First Family, “I don’t know how many times I’ve sang for the president, but every time feels like the first time.”

Justin tweeted about the special evening, writing: “Great night! President Obama is one cool Prez. … He told me he was ‘chillin.’ #PresidentialSWAG”

The night of Christmas carols had an underlying theme of a “season to celebrate miracles.” The President referred to the Christmas story, saying, “Those are values that are shared by all faiths. Let us all rededicate ourselves to each other in that spirit.” Check out his speech below. 

The special event will air on TNT on December 16.
