Fox has issued a press release detailing air dates and plot summaries for the remaining episodes of The Simpsons for the season. This includes more information on the special guest appearance by Lady Gaga in the season finale which airs Sunday, May 20.

“Lisa Goes Gaga” – Season Finale: Lisa tries to reverse her status as one of the least popular girls in school by ghostwriting positive things about herself on the school blog. When her plan backfires, her social ranking plummets to a new low – until a psychic force tells Lady Gaga (guest-starring as herself) that Lisa needs her help. With Gaga’s assistance, Lisa and the entire town of Springfield realize that being yourself is better than being like anyone else.

Previous reports revealed that we can expect new, original musical numbers in a few of these final shows. Which episode are you most looking forward to?
