Lady Gaga has confirmed she will be appearing as herself in a new episode of the Simpsons.

The singer and gay rights campaigner will descend on Springfield after learning of the town’s low self-esteem, and will take precocious Lisa under her wing and tries to empower her through song.

Yeardley Smith, who voices Lisa on the show, told US theatre magazine “This is extraordinary! I’m stunned that she has time in her schedule that she’s coming to our studio to record.

“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.”

Matt Groening told Entertainment Weekly: “Since the very beginning, I’ve always wanted to have on the most iconic personalities of our time, and she’s it.”

Executive producer Al Jean hailed her appearance as a first, saying: “For the first time in the history of The Simpsons, we are honored to have on a show business legend who is younger than our show.”

Lady Gaga added: The 25-year-old told Entertainment Weekly: “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 humour.

“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.”

Lady Gaga revealed that her character ends up kissing Marge.

She joked: “The apple doesn’t fall far from my artistic tree”.
