Britney Spears and Kesha at Wango Tango festival

Britney Spears was the guest-host of the KIIS FM Wango Tango musical festival. The pop princess wore a strapless dress with a geometric print paired  with black boots.  Other celebrities in attendance included Joe Jonas, Jennifer Lopez and Paris Hilton.

See photos below of Kesha — who said she wanted to “pounce” on Britney to get her to do an on-stage collaboration.

Kesha gave MTV pointers of using a glitter gun. “Do not spray yourself in the face with it,” Kesha said. “Do spray everybody else with it. That’s pretty much it.”
