Gaga to guest star as herself on The Simpsons

Grammy winner Lady Gaga is heading to Springfield for a guest gig on TV's The Simpsons, the show's star Yeardley Smith told Smith (who voices Lisa Simpson and currently appears in off-Broadway's Love, Loss and What I Wore) is returning to Los Angeles on August 22, her day off from the play, to record the episode with the singer.

"This is extraordinary! I'm stunned that she has time in her schedule that she's coming to our studio to record," Smith said. Previewing Gaga's storyline, the actress said, "She's playing herself, and [The Simpsons 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."

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

Smith should have plenty of conversational fodder, given Gaga's love of Broadway, Smith's current fashion-centric off-Broadway role and her plans to launch a shoe line. "I can't wait to see what she wears!" the actress exclaimed.
