"What Jhumka?" is a song from the Bollywood movie "Rocky Aur Rani Kii Prem Kahaani". The song is sung by Arijit Singh and Jonita Gandhi and is a reboot version of the iconic song "Jhumka Gira Re" sung by Asha Bhosle. The song features Ranveer Singh and Alia Bhatt and is an extravagant dance number that has become an instant hit. The music composer Pritam has said that "What Jhumka" is an homage to "Jhumka Gira Re" and that the initial idea was to only have the instrumental melody of the song, but later Arijit Singh wanted to actually sing the song.
