Y100 Jingle Ball 2010

Always cutely costumed pop singer Katy Perry was definitely the highlight of the evening at Y100’s Jingle Ball 2010!

In front of the packed BankAtlantic Center audience Katy performed and seemed as jolly as could be in her fun Santa Claus outfit, boots and hat.

Crooner Enrique Iglesias also had the crowd energized as he performed with rapper Pitbull and even brought a fan on stage…and got her to grab his bum!  Hope girlfriend Anna Kournikova didn’t mind as she hung out backstage!

Possibly the best dressed of the evening was Kim Kardashian, showing off her ample curves in a Ronald Abdala corset detailed dress…
