"Who's Laughing Now" is a song by American singer Ava Max, released on July 30, 2020, through Atlantic Records as the second single from her debut studio album, Heaven & Hell (2020).

The song was written by Max, Madison Love, Måns Wredenberg, Noonie Bao, and producers Cirkut and Lotus IV.

Max first teased "Who's Laughing Now" on her social media accounts on May 28, 2020,[1] before officially announcing the single's initial June 2, 2020 release date, and cover art the next day.
