Move over Marge, Patty, Selma, Lisa and Maggie, because Lady Gaga is headed to Springfield to guest on an episode of the 23rd season of 'The Simpsons.' Yeardley Smith, who voices brainy character Lisa Simpson, told Broadway.com that Gaga will appear as herself on the animated series.

Smith said she returned to Los Angeles yesterday, Aug. 22, to record the episode with Gaga. The episode is titled "Lisa Goes Gaga."

"This is extraordinary! I'm stunned that she has time in her schedule that she's coming to our studio to record," Smith said.

Gaga has carved time  in her schedule for practically every media outlet known to man, and appearing on 'The Simpsons' felt like the one thing she has yet to do, but should. The only thing that Gaga hasn't done during the 'Born This Way' press blitz is 'Sesame Street' so perhaps that's next on her docket? Mother Monster vs. Cookie Monster? Okay, we're getting ahead of ourselves here. Remember Katy Perry did it -- despite never being aired.

Smith said that Gaga will play herself and that the show's 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." If Lady Gaga can't bring a smile to the face of little Lisa Simpson, who is the show's voice of reason, no one can! More importantly, what will the animated Gaga wear in her 'Simpsons' turn? And how will she interact with Homer, if at all? Could you imagine that exchange?

"I make music, but I don’t do voice-overs every day of the week, and their characters are so awesomely convincing and sincere and wild and funny, I had to remind myself constantly of the sincerity of the humor,” Gaga told EW about her guest spot.  “That’s what I was trying to focus on, not putting on a character too much and really being as sincere as I could with the lines.”

She also dubbed her guest spot  "one of the coolest things I’ve ever done." She also said that Papa Germanotta is "probably going to do 80 backflips when the episode comes out." We take it he's a big fan of 'The Simpsons.'

Technically, the character of Gaga has appeared on the series before, as Elton John's date to the Golden Globes (pictured above). But Gaga did not voice herself in that episode, so this is her first "official" appearance.

No word as to when this episode of 'The Simpsons' will air.
