There's a saying that you know you are famous when you've been turned yellow on "The Simpsons". Some of "Glee" cast will exactly get this treatment when the Emmy-winning show returns this Fall on FOX. Several promo pictures have revealed which of the singing lots would be animated.

Lea Michele's Rachel Berry is one and Cory Monteith's Finn is another. These two main characters will only be joined by their friend Amber Riley's Mercedes. The actors behind the "Glee" characters have provided voice for the animated figures.

The episode is called "Elementary School Musical" and it would be the first of season 22 which airs September 26. Marge sends Lisa to a performing arts camp where she gets hooked on her new, hip lifestyle. Once back in Springfield, all Lisa can think about is returning.

Playing the camp's counselors are Flight of the Conchords' Jemaine Clement and Bret McKenzie who also voiced their own cartoon version.
