New York City's legendary Madison Square Garden has hosted thousands of performers over the years, but the star power at Z100's Jingle Ball 2006 on December 15, 2006, was impressive even for such a storied venue. Everyone from Nick Lachey to Nelly Furtado to the Killers to surprise guest Timbaland came through to give Z100 listeners the concert of the year. How stellar was the lineup? Even rock god Jon Bon Jovi showed up to catch the show!Make sure to come back on Tuesday for even more great photos!
