Bad Bunny plays the NYC subway with Jimmy Fallon after partying with AOC

Some subway riders got more than they bargained for on Monday: an intimate Bad Bunny concert inside a crowded midtown station.

The Puerto Rican star surprised commuters with an appearance at the Rockefeller Center station alongside Jimmy Fallon.

Videos posted to social media captured the pair performing a cover of “I Want It That Way” by the Backstreet Boys in disguises before ripping them off to reveal their identities to the audience that formed around them.

“Welcome to New York City! I’m Jimmy Fallon, this is Bad Bunny!” Fallon says in the video. “He’s got a new record out!”

Bad Bunny then goes on to sing songs off of his new album, “Debi Tirar Mas Fotos,” including the setting-appropriate “NUEVAYOL” — a tune about New York City and the Puerto Rican diaspora here.

The "King of Latin Trap" is slated to co-host The Tonight Show with Jimmy Fallon Monday night, as well as to perform from his new album, released on Jan. 5.

The subway concert came one day after the singer visited Toñita's social club in Brooklyn, a gathering space for the Caribbean community in the area mentioned in the song — and where he danced in a crowd with Democratic representatives Alexandria Ocasio-Cortez and Nydia Velázquez.

Fallon has performed with other stars in the subway, including Miley Cyrus and Green Day.
