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 [1], and last year he brought along Reese Witherspoon and Miss Piggy [2] to join in the fun. For his final appearance at the annual ceremony on Thursday night, Barack invited Eva Longoria [3], Marc Anthony [4], Chance the Rapper, Kelly Clarkson [5], and more to help him celebrate the season alongside First Lady Michelle Obama [6], 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 [7] when they leave the White House.
