(Cover) - EN Showbiz - Lady Gaga is set to star in the upcoming season of The Simpsons.

She will play herself in an episode where she tries to cheer up Lisa Simpson to no avail.

The animated singer apparently stops in the Simpson's home town after learning that it is filled with low self-esteem.

She then tries to bring some joy into Lisa's life through the power of speech, song and a flash mob.

Yeardley Smith who voices the character of Bart's sister says it was a pleasure to work with the Bad Romance singer.

"I'm stunned that she has time in her schedule that she's coming to our studio to record," Yeardley gushed.

She added that Gaga's character on the show was the "happiest, most optimistic person in the world."

The controversial singer taped her episode yesterday for her trip to Springfield but it is not yet known when the episode, titled Lisa Goes Gaga, will air. (C) Cover Media
