Held Saturday, March 27th and aired live at Nickelodeon, the event attracted Hollywood’s biggest star beginning with host Kevin James known best for his roles at Paul Blart: Mall Cop and The King of Queens.

Famous for his hilarious antics, Kevin James who is also starring in the upcoming movies Zookeeper and Grown Ups even posed backstage covered with green slime!!! But don’t worry, not everyone was covered in slime, at least in the beginning.

Seen on the red carpet (actually, it was orange this time) are Katy Perry who was wearing a rainbow chainmail corset dress from The Blonds Fall 2010 collection. Later, she changed her wardrobe to a yellow mini dress with blue flowers and dyed her hair blue.

Rihanna arrived in a long-sleeved beige mini dress but changed to a gray and pink French maid-inspired outfit for her performance.

The Jonas Brothers, Taylor Lautner, Cory Monteith and brothers Dylan & Cole Sprouse had the hearts of young girls go pitter-patter when they arrived.
