Rahat Fateh Ali Khan will sing for the India's most famous  musician and composer, A. R. Rahman for the soundtrack of the much-awaited Indian musical film ‘Rockstar’ starring Ranbir Kapoor and Nargis Fakhri who is a half Czech and half Pakistani model. The soundtrack album will have 6 songs.

According to Rahman, “Rockstar is a character driven film and as one can guess from the title, there will be lots of guitar. In brief, the music will have very different vibrations.”

A. R. Rahman has only worked with two Pakistani singers, Nusrat Fateh Ali Khan and Shiraz Uppal. This time Rahat Fateh Ali Khan will associate with Rahman for the first time through this film.
