The Surprising Celeb Voices Behind Your Favorite Cartoon Characters

DreamWorks' adorable new CGI romp Home arrives in theaters today. It's the story of a girl named Tip who harbors an alien fugitive named Oh, and the two overcome their differences to become the best of friends. It's a tale as old as time, but the studio managed to cast a unlikely set of stars to bring the two leads to life: Oh is voiced by Jim Parsons, and Tip is played by none other than Rihanna. 

Animated movies have a rich history of amazing stars lending their vocal talents to characters. You're probably familiar with the big ones — and maybe you can even identify certain actors by their voices alone. Tom Hanks as Woody in Toy Story and Angela Lansbury as Mrs. Potts in Beauty and the Beast immediately spring to mind. 

When it comes to these other characters; however, the celeb who lent his or her voice to the role might come as a huge surprise. Keep on clicking for some major animated shockers. Can you even imagine Angelina Jolie or Rihanna in the soundbooth, being told to read a line with more emotion? Who has that job?
