In today's installment of Six Degrees of Separation, we're connecting a girl with an amazing voice and a guy whose voice we can recognize anywhere! What do we mean? Well, we're linking up two Hollywood A-listers and Kids' Choice Awards nominees, Katy Perry and Jim Carrey! These two may seem to be totally different aside from their big KCA nods, but we know a few things they have in common...co-stars!

Let's start with Katy Perry's KCA-nominated role in The Smurfs, which she starred in alongside Neil Patrick Harris, who was in Beastly with Vanessa Hudgens, who was in Sucker Punch with Abbie Cornish, who was in Limitless with Bradly Cooper, who was in Yes Man with Jim Carrey!

Maybe these two outrageous stars aren't so different after all! Are you voting for Katy and Jim? Hurry up, before the KCAs kick off this Saturday!
