The annual children's ceremony will be hosted by KING KONG star Jack Black on 1 April (06) at UCLA's Pauley Pavilion.

Black enthuses, "I'm super excited to be hosting Nickelodeon's Kids' Choice Awards because when you're doing a show for the kids, you can get extra crazy and loony. I have a lot of secret plans for when I host the awards, but I can tell you I'm going to bring the super-duper, freaky-deaky, ultra-clowny super dance! But that's all I'll say."
