What do Robert Downey Jr., Katy Perry and a few hundred gallons of green slime have in common?
The stars – along with Tina Fey, Steve Carell, Chris Rock, Jackie Chan, Jonah Hill, Queen Latifah, David Spade, Lea Michele, Dev Patel, Miranda Cosgrove, Shaun White and more – are set to help host Kevin James dole out Nickelodeon’s 23rd Annual Kids’ Choice Awards this Saturday.
In addition to Rihanna and Justin Bieber performing, eight-time Olympic medalist Apolo Anton Ohno will attempt to set a new world record for being catapulted into the show’s trademark green slime via the Kids’ Choice Awards Slime Slingshot.
The awards will be telecast live from UCLA’s Pauley Pavilion on March 27 at 8 p.m. (ET/PT). Until then, kids can cast their votes online in 19 categories including favorite couple, movie actor, singer, athlete and reality show.
