Who do you defines as celebrity? Actor and actress, model, singer, athlete, and presenter must be on top of your list. Then how about cartoon characters? Why don't consider them as celebrities too, especially because a lot of them have a resemblance look with our favorite public figures.
See these below pictures of some celebrities and cartoon characters look-a-like. This is another proof, besides Celebrities without Makeups, that celebs are not all beautiful and glamor.
Feel free to add in the comment if you've got another idea of cartoon character - celebrity look a like.
