//Katy Perry, Chris Brown, Akon And More Perform At KIIS FM’s Jingle Ball 2008//

Katy Perry made her grand entrance onto the stage at KIIS FM’s annual Jingle Ball concert being expelled from the inside of a huge banana while her band played the Cyndi Lauper hit “Girls Just Wanna Have Fun” before jumping into her own current hit “Hot N Cold.”

  

A bunch of the 2008′s hottest acts also took the stage at LA’s annual holiday potluck concert including Chris Brown (who had a very special guest during his set), Akon, Pussycat Dolls, Estelle, Jesse McCartney, David Banner, and Tokio Hotel.

 

Chris Brown – Wanna take a guess at who his special guest was? Go ahead. Your first guess is probably correct. Stumped?

 It’s Rihanna. Duh! Christopher Robyn got together to perform the “Umbrella” remix.

 

Akon

Pussycat Dolls – The girls shimmied through their performance of their summer hit “When I Grow Up.” Click here for a short clip.

 

 

Estelle

 

Jesse McCartney

 

David Banner – DB love the kids! He also loves his audience. He performed through the crowd on top his bodyguard’s shoulders.
