The music video features Deepika Padukone as Mastani dancing in a grand hall surrounded by 20,000 mirrors.

For the song, she wears a heavy golden anarkali lehenga, and sings directly to Ranveer Singh (as Bajirao), expressing her love for him while he watches her happily.

The song was inspired by "Pyar Kiya To Darna Kya" from Mughal-e-Azam and thus was observed as its modern version, while Deepika was compared to Madhubala.
