Madison Square Garden was on fire last night as some of the most iconic and emerging artists that took stage for New York's hottest event of the holiday season. One of the night's biggest surprises happened when Selena Gomez shocked audiences by joining Zedd on stage to perform "I Want You To Know." After Hailee Steinfeld performed, she was surprised backstage by friends and family who came out to celebrate her 19th birthday. Steinfeld was speechless as she was presented with a birthday cake and other surprises. Fetty Wap made his first Jingle Ball appearance of the 2015 tour, performing hits like "My Way" and "Trap Queen" on a giant throne. DNCE was in the holiday spirit all night long, enlisting a dance crew of Santa's that took stage during "Cake By The Ocean." Charlie Puth followed suite with the holiday cheer, serenading the sold-out crowd with a rendition of "I'll Be Home for Christmas." To close out the night, The Weeknd had fans on their feet and singing along to the hit "The Hills" and "Can't Feel My Face."
