Justin Bieber Performs And Ke$ha Plays With Stuff At Wango Tango

Usher, his dangerous protégé, Justin Bieber, Adam Lambert, Ryan Caberera, and other artists performed at KIIS-FM’s Wango Tango at the Staples Center in LA on Saturday night (May 15).

Usher did what he does best and sang dirty and got his grind on with some female dancers and the mic stand, Lambert performed his new single “If I Had You”, and Ke$ha brought out a breast cake for a band members birthday which started a cake fight on stage. Check out some of the performances after the jump.

Ludacris took his date Conjure down the red carpet, and David Hasselhoff continued the weird show and tell theme by sharing his dinky camera while Ke$ha brought a human head…a fake one, only because she doesn’t have enough pull to secure a real one. Some of the ladies from The Hills posed together which is confusing because on Tuesday’s episode Kristen Cavallari hated Stephanie Pratt and it’s another reminder that I really need to stop watching that show. Speaking of reality shows, I’m thinking it’s only a matter of time before the grown up (sort of) Kylie and Kendall Jenner, who walked the red carpet, get their own one. That sex tape just continues to give.
