After Ra.One's superhit song Chammak Challo, Shahrukh felt that the film needed another hit track. So, finally SRK and Lady Gaga have decided to work on another song, which will be used as part of the post-release promotions for RA.One.
Initially, when SRK wanted to rope in Lady Gaga for Ra.One, things fell flat and didn't work out due to date issues. The source explained, "Either Shah Rukh was busy with the post-production of RA.One or Lady Gaga's dates couldn't be worked out. The song couldn't be shot for the film, although composers Vishal-Shekhar had already composed a tune for Lady Gaga to record."
So, now when time is no factor for the duo celebs, Ra.One would gets it's another brand new hit track.
