Also performing were Rihanna, Peter Wentz and The Fallout Boys, The Veronicas, Shontelle, and Jesse McCartney.

This concert must be in relation to yesterday’s Z100 Jingle Bell concert where Jesse, Katy and Rihanna performed as well.  The clothes are different so it must be a different venue, lol.

Lots of pics after the jump
