"I thought it was stupid for me to leave without coming out and saying thank you for being here and standing in the f**king pouring rain," she told the crowd.

The Happier Than Ever singer then took the stage with her brother, Finneas O'Connell, to perform a six-song acoustic set in place of the full-length show.

The stripped-down renditions, which included tracks from across her discography, were praised by fans in attendance.

During the acoustic set, Eilish sang ocean eyes, when the party's over, everything i wanted, TV, lovely, and Happier Than Ever.

"That was truly really special for me. I love you so much," she told the crowd.

The full show has been rescheduled for Thursday night.

The singer is slated for two more performances in Mexico, with a show in Monterrey on Friday and Guadalajara on Saturday.
