In this batch of pictures from the 2011 Nickelodeon Kids' Choice Awards, check out some of the amazing, and sometimes hilarious, performances. As most people who tune in know, the Kids' Choice Awards are all about having fun. So when Jack Black runs out for a dance break with the Black Eyed Peas, don't be too confused.

The Black Eyed Peas performed their hit song 'The Time (Dirty Bit),' and comedian Jack Black ran onstage for their running man breakdown as the 'Dirty Bit' kicks in. Big Time Rush and Snoop Dogg also took the stage to perform their hit song 'Boyfriend,' and the rapper definitely got more than he bargained for, as he was sprayed with gallons of green slime at the end of the performance. Willow also dazzled viewers with a mashup performance of her tracks '21st Century Girl' and 'Whip My Hair,' as she took flight over the crowd of screaming kids gathered in the audience.

Check out all of the pictures from the performances of the 2011 Kids' Choice Awards, and watch BEP's performance.
