With all the twisted, weird and scandalous relationships that define Gossip Girl, who better than to perform live on the show than a rumored hermaphrodite?

The rising pop star sings, “Bad Romance,” at a private show arranged by Blair, who is trying to prove herself as a freshman at NYU, on Monday's new episode.

Hopefully, they get through the episode without a Lady Gaga nude scene, or her staging her own death on stage. Although it's Gossip Girl, you never know.

“My little sister is the hugest Gossip Girl fan ever,” said Lady Gaga, who wears a 30 foot-long dress for her concert. Naturally. Would you expect any less?

She says it's a "crazy performance art piece" in which she, via her song, serves as the narrator for what the characters are doing. Intrigued? Confused?

Us to. Check out the preview of Lady Gaga on Gossip Girl below ...
