'The Simpsons' finale: Lady Gaga performs a Little Monsters song with a jet-pack bra

For "The Simpsons" Season 23 finale, pop/dance sensation Lady Gaga lends her voice when she guest stars as herself. When Lisa's get-popular scheme backfires and her popularity plummets to an all-new low, Lady Gaga receives a psychic force telling her Lisa needs help.

Gaga bursts into town to help Lisa and all the Springfieldians realize that being yourself is better than being anyone else, in an episode titled "Lisa Goes Gaga," airing Sunday, May 20 at 8 p.m. ET/PT on FOX.

Check out these preview clips. In the above clip, Gaga (in a hummingbird-turned-Grammys dress) performs a "Little Monsters" song dressed a little bit like "Vogue"-era Madonna. In the below clip, Gaga advises Lisa that she needs a flash mob.
