WASHINGTON (AP) — The Obamas celebrated the holiday season with musical stars Justin Bieber, Cee Lo Green, Jennifer Hudson, Victoria Justice and the Band Perry at the 30th annual "Christmas in Washington" concert Sunday night.

President Barack Obama, his wife Michelle, daughters Malia and Sasha, and mother-in-law Marian Robinson attended the concert to benefit the Children's National Medical Center.

The concert of Christmas carols and songs— which took place at the National Building Museum— was hosted by comedian Conan O'Brien.

In honor of the "season to celebrate miracles," Obama spoke about the story of Jesus' birth during his brief remarks to the crowd.

He said the story of Jesus Christ has changed the world by teaching basic values such as loving one another, helping and serving the less fortunate, forgiving, drawing closer to family, being grateful and keeping faith.

"Those are values that are shared by all faiths," Obama said. "So tonight let us all rededicate ourselves to each other, and in that spirit, from my family to yours: Happy holidays, Merry Christmas, God bless you all, and God bless the United States of America."

Before the concert, the Obamas greeted patients of the children's medical center dressed as elves and presented them with a basket of children's books. Obama playfully struggled to lift the basket and asked the elves to help him place it under a Christmas tree.

Other entertainers included the United States Naval Academy Glee Club, Washington Youth Choir, American Family Choir, United States Army Band Herald Trumpets, Ian Fraser and the Christmas in Washington Orchestra.

The concert will air Friday on TNT.
