The song underwent changes to suit the nativity of North India, an example being the change of "Ringa Ringa" to "Dhinka Chika". Composer Anu Malik alleged that the song "Character Dheela" is an unauthorised copy of his "Mohabbat Naam Hai" from the 2001 film Ajnabee.

The songwriter Turkish Mohammed Azam filed a plagiarism suit against Pritam, claiming the lyrics for "Character Dheela" were copied from a song he wrote in 2007.
