WATCH: ED SHEERAN & JASON MRAZ Take The Stage - TOGETHER!

For the first time, Z100 decided to host a viewing party for fans who couldn't buy tickets for the radio station's actual Jingle Ball, which featured artists like Justin Bieber, One Direction, and Taylor Swift. Viewers gathered around in the hundreds not only to watch Z100's Jingle Ball on an enlarged screen, but to also exclusively receive their own performances that hadn't been conducted at the Jingle Ball concert. This included a very special, intimate performance by Ed Sheeran and Jason Mraz at the MSG Theater.  

Much to the surprise and gratitude of the supportive fans at the Jingle Ball viewing party, Sheeran and Mraz together performed their own version of "Empire State of Mind," originally by Jay-Z and Alicia Keys. The performance can be seen above!

Z100's Jingle Ball viewing party was hosted by Disney Channel's Bridgit Mendler (who also performed for the audience), Z100's Trey Morgan and other Z100 DJs. Constantly keeping viewers interested and entertained, the hosts also gave away several tickets to audience members to actually attend Z100's Jingle Ball, only a couple of feet away. Along with the performance of Jason Mraz and Ed Sheeran, several artists made appearances to speak to fans, including Hot Chelle Rae and FUN.
