Kids' Choice Awards Preview! See Which Stars Have Won the Big Help Award

See which celebs have been honored at the Kids' Choice Awards for their charitable deeds.

Nickelodeon's Big Help initiative encourages kids to help people, animals and the planet.

And every year since 2009, during the Kids' Choice Awards, they have handed out The Big Help Award to a charitable celeb who is leading by example. Who will it be this year? We'll find out on Sunday!

To distinguish the award (formerly known as "The Big Green Help Award"), honorees are given a different color blimp than the rest of the evening's award winners.

In 2009, 2010 and 2011, the award was green. In 2012, they changed the color to silver.
