Lady Gaga is heading to Springfield for a guest gig on The Simpsons.

Yeardley Smith (who voices Lisa Simpson) told Broadway.com, “This is extraordinary! I’m stunned that she has time in her schedule that she’s coming to our studio to record.”

Previewing Gaga’s storyline, she continued, “She’s playing herself, and the writers describe her as the happiest, most optimistic person in the world. She comes to Springfield to try to cheer up Lisa, but she can’t.”

Gaga’s appearance will air during the animated hit’s upcoming 23rd season.

And where does this guest spot rank among her professional experiences? “I would say this is one of the coolest things I’ve ever done,” says Gaga.

“My dad’s probably going to do 80 backflips when the episode comes out.” He and the rest of America will be treated to a full-on animated extravaGaganza, complete with a Gaga Express train powered by a giant flame-shooting bustier, ample wardrobe changes, and a kiss with… Marge! “I play a little bit of a slut,” quips Gaga. “The apple doesn’t fall far from my artistic tree.”

In a previous episode, an animated version of the “Bad Romance” singer (not voiced by Gaga) appeared on the show as Tony winner Elton John‘s date to the Golden Globe Awards.

Excited! Too bad King of the Hill isn’t still producing new episodes.
