'Glee' peek at 'The Simpsons'-ization of Rachel, Finn and Mercedes

"The Simpsons" has done musicals on FOX long before "Glee," so naturally it was time for a few Gleeks to cross over and add to the love.

In the 22nd season premiere of "The Simpsons" on Sept. 26, Lisa gets sent to a performing arts camp and begins a newfound love of showbiz.

Who else is there loving the spotlight? Rachel, Finn and Mercedes of course! Lea Michelle, Cory Monteith and Amber Riley voice the animated versions of themselves on the episode "Elementary School Musical."

Before we get to hear them though, here's a first look at the "Simpsons"-ized Gleeks:

Rachel even has the same attitude and arm placement.

Finn has the same fashion sense.

And we see that Mercedes still has a love for graphic-print Ts.

Also appearing on the episode are "Flight of the Conchords'" Jemaine Clement and Bret McKenzie (and you can see their "Simpsons"-ized photo in our Fall TV Returning Shows guide).
