Hey Hey Hey

"Hey Hey Hey" is a song recorded by American singer Katy Perry for her fifth studio album Witness (2017). It was sent to Italian contemporary hit radio stations on January 12, 2018 by Universal Music Group as the album's fifth single. The song was written by Perry, Sia, Sarah Hudson, Max Martin and Ali Payami, while production was handled by Martin and Payami. "Hey Hey Hey" is a rock- and electronica-influenced, dark electropop track about female empowerment. Reviewers speculated that the song was also about the 2016 United States presidential election nominees Donald Trump and Hillary Clinton.

Music critics gave mixed reviews of "Hey Hey Hey", with some praising it as one of the highlights of Witness and others deeming it mediocre. It was also compared to the works of American singer Britney Spears and New Zealand singer-songwriter Lorde. To accompany the track, a music video was uploaded onto Perry's official YouTube account on December 20, 2017. The clip was filmed by Isaac Rentz in Beverly Hills, California and is set in the 18th century and the Ancien Régime, with the singer's outfits resembling those of the last Queen of France before the French Revolution Marie Antoinette and French heroine Joan of Arc. For further promotion, Perry gave several live performances of "Hey Hey Hey", including those during her concert tour Witness: The Tour (2017–2018) and her four-day YouTube live stream Katy Perry Live: Witness World Wide (2017). Commercially, the song appeared on charts in Czech Republic, New Zealand and Sweden.
