(USA Today) - Lady Gaga, who is busy on her world tour and arrived in Japan on Tuesday, is featured on the upcoming season finale of The Simpsons.

Gaga plays herself in the May 20 episode, in which she changes into 18 different outfits! Go, Gaga.

According to show's synopsis, the plot will revolve around Lady Gaga coming to Springfield "to cheer up a dejected and depressed Lisa."

She arrives in the Simpsons' hometown of Springfield aboard the Gaga Express train, powered by a giant flame-shooting bustier.

Gaga taped the voice-over back in August, at the time admitting it was "a little nerve-wracking." She told EW.com, "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.
