Lorde debuted her forthcoming single "What Was That" at a pop-up event in New York's Washington Square Park Tuesday night, about two hours after police had shut down the gathering due to overcrowding.

The superstar confirmed on social media the song will drop at Midnight April 24, marking the rollout for her first album since 2021.

Lorde's surprise performance of her new song 'What Was That' was shut down by the New York City Police Department, with a representative telling EW the pop star 'did not possess' a permit.
