See One Direction, Jason Mraz, the Wanted, and other stars goof off backstage at Madison Square Garden
Before opening the show, Harry Styles, Louis Tomlinson, Niall Horan, Zayn Malik, and Liam Payne visited the Artist Holiday Portrait Studio at Z100's Jingle Ball 2012, presented by Aeropostale, at Madison Square Garden on Dec. 7, 2012 in New York City. "[This is] crazy," Tomlinson gushed to Us of the concert. "We never thought when we started out that we'd be here."
