Over the last few years, President Barack Obama has always ensured that the National Christmas Tree Lighting Ceremony is a spectacular affair. In 2014, he broke it down with Fifth Harmony, and last year he brought along Reese Witherspoon and Miss Piggy to join in the fun. For his final appearance at the annual ceremony on Thursday night, Barack invited Eva Longoria, Marc Anthony, Chance the Rapper, Kelly Clarkson, and more to help him celebrate the season alongside First Lady Michelle Obama, and their daughter Sasha. The event, which took place at the Ellipse in President's Park, was full of laughter and song and included more than a few adorable moments between the president and the guest of the hour: Santa! They hugged, belted out a few carols, and reminded us all over again of how much we're going to miss the Obama family when they leave the White House.
